The short answer: routes matter more than bandwidth
The most overlooked part of speeding up AI art tools is the long-lived connection between Midjourney and Discord. Midjourney has no standalone client — everything happens inside a Discord bot session: commands go from the client to the gateway, reference images upload as attachments, and results come back as attachments. When that chain breaks, the symptom isn't a page that won't load; it's a /imagine command that gets no reply, an upload that stalls at some percentage, or a queue that kicks you back to the login screen halfway through.
Break the flow into stages and the three failure types each have their own cause:
- Login stage: the client has to complete the TLS handshake, open the gateway WebSocket and confirm heartbeats; a timeout at any step sends you back to the login screen.
- Upload stage: reference images go up as HTTPS chunks, and a single lost chunk means a retransmit, so the progress bar looks frozen.
- Output stage: the bot pushes results over that same long connection; if the connection resets, the queue time you already waited is wasted.
So judging whether a route suits image generation isn't about peak bandwidth — it's about three things: whether the handshake completes first time, whether uploads retransmit midway, and how long a session survives.
Why Discord decides the render experience
Discord's desktop and web clients both keep a session alive through a single WebSocket gateway connection. Once connected, the client sends heartbeats at fixed intervals and the server acknowledges them; if network jitter drops a heartbeat, the client tries to resume the session, and if resuming fails it runs through login again. The longer you sit in a render queue, the more chances that connection has to break. That's why a route that feels fast for everyday browsing can still drop you mid-render.
Command path
A slash command is one round trip from client to gateway to bot. Those packets are tiny, so bandwidth barely matters — packet loss and handshake latency do. On a lossy route, commands show as the application not responding, or get no acknowledgement at all.
Attachment path
Reference images upload through Discord's attachment CDN, which is a different connection from the gateway. If those CDN domains don't match a proxy rule, they go out directly, and the bot receives the command but never gets the image. That's the most common reason a command works but no image appears, and the first gap to close in your routing rules.
Session persistence
While a render is queued, the client has to stay connected. System sleep, network switching and proxy reconnects all interrupt the session. Change your exit IP midway and the server may ask you to verify again, losing your place in the queue. Stability over a long session matters more than any instantaneous speed number.
# Routing rule example: send Discord and Midjourney through the proxy, everything else direct
DOMAIN-SUFFIX,discord.com,PROXY
DOMAIN-SUFFIX,discordapp.com,PROXY
DOMAIN-SUFFIX,discordapp.net,PROXY
DOMAIN-SUFFIX,midjourney.com,PROXY
DOMAIN-SUFFIX,cdn.discordapp.com,PROXY
GEOIP,CN,DIRECT
MATCH,PROXY
Rule order changes what matches: domain rules must come before GEOIP and MATCH, otherwise attachment domains can hit the catch-all rule first and get sent out through an exit that doesn't suit them. After editing rules, restart the client once so existing connections are rebuilt.
Direct, relay and dedicated: route differences
Run the same login → upload reference image → wait for output flow over the three route types and the differences cluster around handshake, upload and session persistence. The table below is qualitative and deliberately omits latency figures: the same route behaves differently at different times of day, and a fixed number would mislead.
| Stage | Direct | Standard relay | IEPL dedicated line |
|---|---|---|---|
| Discord login handshake | Gateway connection often needs retries; verification triggers frequently | Usually succeeds first time; occasional timeouts at peak hours | Stable handshake, few reconnects |
| Reference image upload | Frequent chunk retransmits; progress sits mid-way for a long time | Small images fine; large images slow at busy times | Steady upload rate; large images rarely interrupted |
| Result delivery | Long connection easily reset; you have to rejoin the queue | Generally usable; long queues may drop | Sessions last; queued jobs rarely interrupted |
| Best for | Occasional message checks | Everyday image generation, light use | Batch generation, long unattended queues |
The problem with a direct connection isn't a speed ceiling, it's an uncontrolled path: when international exits congest at peak hours, packet loss and jitter arrive together, and that's exactly when WebSocket heartbeats drop. A standard relay fixes the path and is enough for everyday rendering, but relay nodes are shared, so upload rates fall noticeably at busy times. An IEPL dedicated line runs on its own channel and doesn't compete for bandwidth with public exits; its advantage shows in long queues and batch generation — the cases where you can't afford a drop.
Choosing an exit region: Japan, Singapore and the US West Coast
There's only one goal when picking a region: put your exit closer to Discord's edge nodes while keeping it stable. By typical results, Japan and Singapore are the first choices for users in Asia, while the US West Coast suits people who also need other overseas services. European nodes aren't unusable — the round trip from Asia is simply longer, and long-session stability suffers.
A fixed exit IP matters more than the “fastest node”
Discord records the network environment you log in from. Jump between countries often and the account may be asked to verify again, interrupting queued sessions. Once you pick a region, try to complete a whole rendering round on the same exit; with several devices, have them share one region instead of each connecting somewhere different. Device count itself isn't a burden — simultaneous online devices are unlimited — what you actually need to control is region hopping.
Your account region and exit region don't have to match
Logging in from one region consistently is more practical than matching your sign-up country exactly. What triggers verification is switching continents in a short window, not the region itself. If you really need to change regions, do it when nothing is queued, then restart the client before logging in again.
Keeping the connection alive: six settings that work
The six below are ordered by priority: the first three keep the connection from dropping, the last three help it recover when it does.
- ✅ Turn on auto-reconnect and resume in the client, and don't switch nodes manually while queued.
- ✅ Remove the system's battery restrictions and background freezes for the client — most visible on phones and on laptops after the lid closes.
- ✅ Prefer UDP-based protocols (Hysteria2, TUIC); retransmits cost less on a lossy route.
- ✅ Put Discord and Midjourney domains in the proxy rules and let everything else go direct, cutting concurrency inside the tunnel.
- ❌ Don't switch country nodes repeatedly while waiting in a queue; a changing exit IP triggers re-verification.
- ❌ Don't leave DNS resolution to your local ISP; that causes DNS leaks and makes rules match the wrong branch.
DNS is the item most often overlooked. Handing queries to your local ISP not only exposes which domains you visit, it also feeds wrong answers to your routing rules: if an attachment domain resolves to a domestic address locally, the rules may classify it as direct and the upload then fails. Enabling remote resolution in the client, or pointing DNS at a trusted server, avoids this whole class of problem.
Picking a protocol: TCP or QUIC
A protocol doesn't change route quality, but it decides what recovery costs when the link fails. TCP-based protocols wait for the retransmission timer on packet loss, and head-of-line blocking can stretch a small request into seconds; QUIC-based protocols handle retransmission in user space, so one blocked stream doesn't stall the others — friendlier for uploading large images.
| Protocol | Transport | Behaviour for image generation |
|---|---|---|
| Shadowsocks | TCP / UDP forwarding | Lightweight and low overhead, good for single-device daily use; UDP forwarding depends on server configuration |
| VMess | TCP, WebSocket, gRPC and more | Broad compatibility and many options; connection reuse needs client support |
| Trojan | TLS 443 | Shares the HTTPS port; slightly higher handshake cost, stable over long connections |
| VLESS | TLS / XTLS | Low header overhead, suited to long sessions and many small requests |
| Hysteria2 | QUIC(UDP) | Friendly to lossy links; cheap retransmits when uploading large images |
| TUIC | QUIC(UDP) | Multiplexed; keeps sessions alive well on weak networks |
For everyday single-device rendering, Shadowsocks or VLESS is enough; if your network shows clear packet loss at peak hours, or you upload reference images while queuing, UDP options like Hysteria2 and TUIC show their advantage. The trade-off is that some networks restrict UDP — if you can't connect, switch back to a TCP-based protocol to check before blaming the route. Data inside the tunnel is encrypted to banking-grade standards throughout; the protocol choice affects transport efficiency only, not that layer.
Subscription link and client import steps
A subscription link is a tokenised URL that the client fetches to get the route list. The token works as a credential — don't paste it into public groups. The import flow is much the same on every platform:
- Copy the subscription link from the user panel and check there are no stray spaces at either end.
- Open the client, go to the subscription or profile page, create a new subscription and paste the link.
- Update the subscription and wait for the route list to load.
- Pick a Japan or Singapore node and confirm connectivity once.
- Open the routing rules and point the Discord and Midjourney domains at the proxy.
- Launch Discord and confirm the gateway connection before sending commands.
Platform differences are mostly at the system layer: Windows and macOS clients offer TUN mode, which also captures apps that ignore the system proxy; Android has a persistent connection option that suits long queues; iOS relies on system-level configuration and needs the connection state re-checked after switching networks; Linux users mostly run command-line clients and handle startup and logs themselves. When subscription content updates, just tap update once in the client — no need to re-import.
When a render stalls: a checklist
- Check whether Discord shows connected. If it keeps reconnecting, switch to a backup node in the same region — not a different country.
- Send a normal message as a test. If it sends but the bot doesn't reply, the gateway is fine and the session isn't — just issue the command again.
- Check whether the attachment domains go through the proxy. An upload that stalls at the start usually means the attachment CDN domains aren't matching a rule.
- Confirm the client hasn't been suspended by the system. This happens most on phones sent to the background and laptops with the lid closed.
- If all of the above checks out and it still fails, consider changing protocol rather than swapping nodes again.
Conclusion: spend the budget on stability
Back to the original question: choosing a way to speed up AI art tools follows different criteria from watching video or downloading files. The Midjourney and Discord pairing puts the pressure on long connections, so a route that completes the handshake first time, uploads without retransmits and keeps sessions alive is worth more than one with a higher headline bandwidth. VPNQF offers access in 90+ countries with 220+ routes, unlimited simultaneous devices, support for Alipay, WeChat Pay and USDT, and sign-up with just a username and password — no email address required. Subscriptions come with a 60-day no-questions-asked refund, so you can run through the process above before deciding.
If you only check messages now and then, any route that connects will do; if you generate dozens of images a day with long queues, focus on three things: a dedicated line, a UDP protocol and a fixed exit. Leave the rest to the client's routing rules.
