Most people who search for an AI art VPN are not struggling to reach Midjourney's website. They get stuck in two far more specific places: the Discord client sits on “Connecting” and never finishes, or they join a voice room and cannot make out what anyone is saying. Midjourney puts image generation inside Discord, so a single render passes through three separate paths — the gateway socket, the image CDN and voice over UDP — and if any one of them misbehaves, the whole experience collapses. This article takes the three paths one at a time, shows a connection test you can reproduce yourself, sets out the order in which to choose routes, and explains what VPNFH can and cannot promise in this scenario.
Midjourney's connection is made up of three paths
Judging Discord as a single “fast or slow” whole rarely gives an accurate answer, because it runs three kinds of traffic at once:
- Gateway socket: the client opens a WebSocket to the Discord gateway to send and receive message events. When this connection drops, the UI stays on “Connecting”, slash commands go nowhere, and Midjourney's render progress stops updating.
- API and image CDN: slash commands and message history go over HTTPS, and rendered images are served as attachments from the CDN. If the route is up but images spin forever or open as broken thumbnails, the problem is almost always here.
- Voice rooms: voice and video run over UDP via WebRTC, which is far more sensitive to packet loss and jitter than web requests. This is the usual reason text works but voice drops the moment you join — the proxy only handled TCP and never touched UDP.
Midjourney's web app is a separate entry point: sign-in and rendering go over HTTPS and do not depend on Discord's gateway socket, though images still come from the CDN. So “the web version works but Discord doesn't” is not a contradiction — it just narrows the problem down to one path.
Route types compared: direct, relay and IEPL
The route type sets the ceiling for all three paths. The three are not a simple fast-to-slow ranking; each brings different trade-offs from its path characteristics.
| Route type | Path characteristics | Typical voice-room performance | Best suited to |
|---|---|---|---|
| Direct | Connects straight to an overseas node over the public international gateway | More packet loss and jitter at peak hours, so voice breaks up more often | Rendering only, no voice, no sensitivity to wait times |
| Relay | Connects to a relay node first, then follows an optimized path to the exit | More stable than direct; actual performance depends on congestion in the relay leg | Everyday rendering and text channels, occasional voice |
| IEPL dedicated line | International Ethernet private line that avoids the public gateway | Fixed path, low jitter, steadier over long voice sessions | Long voice sessions, several people rendering at once |
One thing needs saying: route type only affects path quality, not Midjourney's rendering speed itself. Rendering queues on the server side; all the client can do is get commands out, receive progress, and pull images back.
How to run a voice room test
“Testing” does not need lab equipment — just control the variables: same channel, same time window, same actions, changing one condition at a time. Results vary a lot by region, ISP and time of day, so what follows is a reproducible method rather than a set of hard-coded numbers.
- Start with a baseline and no route active: sit in a voice room for five minutes, note any dropouts or robotic audio, then open the connection info in the channel and check the current region, protocol and packet-loss stats.
- With a route active, repeat exactly the same steps: same channel, same time window, same five minutes — change only the route, not the device or the headset.
- Check the protocol in the connection info: if it shows direct UDP rather than going through the route, that route is not forwarding UDP and voice is not actually accelerated.
- Test the image path: have Midjourney render an image in the same channel and watch the attachment from first appearance to fully opening, noting any broken images.
- Test the gateway path: leave the client online for more than half an hour and watch for “Connecting” reconnect prompts.
- Switch to the next route and repeat steps 2 to 5, recording each result as a single line so you can compare them side by side.
- ✅ No dropouts throughout the voice session and steady packet-loss stats in the connection info mean UDP forwarding works on this route.
- ✅ If the rendered image opens the moment it appears, the image CDN leg is clear.
- ❌ Text works but voice drops as soon as you join: suspect the route is not forwarding UDP before you suspect bandwidth.
- ❌ Images spin forever while messages send fine: most likely the CDN domain is not going through the route, or it is resolving to a poor node.
How to verify the exit route is working
Connected is not the same as routed correctly. Three checks cover most cases of “it looks connected but is not actually going through”.
Exit address: open any IP lookup page and see whether the location matches the route you picked. On desktop, note that system proxy and TUN mode behave differently, and Discord as a separate process will not necessarily follow your browser.
DNS resolution: use a DNS leak test page to see which server ultimately handles the request. If resolution still lands with your local ISP, the CDN may be pointed at a nearby but poor node, which shows up as slow image loading.
Per-app confirmation: if your client supports per-app routing, confirm separately which path Discord, the browser and your local drawing tools each take.
Testing only the browser does not count. The Discord client, Midjourney's web app and local drawing tools are three different processes; verify each one rather than inferring the other two from the browser.
Split rules: send Discord through the route, keep local tools direct
Full-tunnel proxying is the least effort, but it makes local drawing tools take a pointless detour and end up slower.
- Allow by domain: discord.com, discord.gg, discordapp.com and discordapp.net go through the route; midjourney.com depends on which entry point you use.
- Allow by process: matching on process is the simplest approach for the desktop client and avoids missing connections opened by child processes.
- Allow UDP too: do not drop UDP in your split rules — when voice traffic is blocked at the rule level, the UI gives no obvious warning.
- Keep local services direct: add the ports that Stable Diffusion WebUI, ComfyUI and similar local tools listen on to the direct list, otherwise loopback traffic takes a detour and comes back.
Route regions and types can be picked from the global nodes page, which labels each region as IEPL dedicated line, relay or direct.
Protocol choice: in voice rooms, UDP support beats encryption
Voice rooms run over UDP, so whether a protocol can carry UDP natively decides the experience far more than the encryption algorithm does.
- Shadowsocks: lightweight and capable of UDP forwarding, but it has to be enabled explicitly on the server; once it is, voice usually travels through the route normally.
- VMess: primarily TCP-based; UDP needs extra encapsulation, which adds overhead and latency, so it has no advantage for voice.
- VLESS: no built-in encryption, relies on TLS, and is very light when configured well; UDP likewise has to be enabled separately.
- Trojan: disguises traffic as ordinary HTTPS, which is friendly to middleboxes and suits complicated network environments.
- Hysteria2 / TUIC: built on QUIC with native UDP transport, steadier voice on weak or lossy networks — provided the matching UDP ports are open on the server.
In other words, if you mostly collaborate in voice rooms while rendering, favor protocols with native UDP support; if you only post commands and collect images in text channels, the differences between protocols are smaller than you would think.
Choosing an accelerator: selection logic and VPNFH's trade-offs
Pulling the criteria together, the order is roughly: first confirm the protocol can forward UDP, then look at route type, and only then at node count. More nodes does not mean a better path — one low-jitter dedicated line beats a pile of congested direct connections.
Where VPNFH sits against that standard: 90+ countries / 160+ routes, with IEPL dedicated lines, relays and direct connections all available, so you can test each one in a voice room as described above and then decide which to use; one account covers unlimited devices, desktop and mobile online at once, with no second subscription just for voice; sign-up needs only a username and password, no email address required; no logs; a 7-day no-questions-asked refund, with payment via Alipay, WeChat Pay and USDT.
Bottom line: for rendering only, with no voice, a direct route is enough; for long collaborative sessions in voice rooms, an IEPL dedicated line or a protocol with native UDP support fits better; judge by the protocol and packet-loss stats in the connection info, not by whether it “feels fast”.
FAQ
Discord still says “Connecting” even with a route active — what now?
First check whether that route handles UDP and long-lived connections. Some networks reset WebSockets that stay open too long; switching routes or moving to a TCP-based protocol usually restores it. If only Discord fails while the browser is fine, check first whether your split rules miss the gateway domains.
Is rendering any different in Midjourney's web app versus Discord?
Same account, and rendering happens on the server either way — the difference is the entry point. The web app uses HTTPS and skips the gateway socket; in Discord there is an extra layer of message delivery, and images still come from the CDN. Use whichever is handier; there is no need to force one because it seems “more professional”.
Do voice rooms drop more often on mobile?
When a mobile network hands over between cell towers, the exit address changes briefly and a system-level VPN has to rebuild the tunnel, which interrupts voice. Setting Discord as a per-app proxy so only it uses the route, and allowing it to run in the background, reduces these interruptions.
