This is the short version. Start at question 1, stop at the first answer that sends you somewhere, and do that fix. The fixes themselves are all in one place, our complete Simple Voice Chat fix guide, so you only read the step you need.
The flowchart
1. Is Simple Voice Chat on the server and on every client?
Both sides need a build for their loader and Minecraft version.
- No: install matching builds first. The fix guide's Common mistakes section has the version check.
- Yes: go to 2.
2. Does the console say "Voice chat server started at" your port after a full restart?
- It says
Failed to run voice chat at UDP port, or a modded server stops right after starting (on Paper the plugin switches itself off instead): another program holds the port. Do step 4 of the fix guide. - There is no voice chat line at all: the mod or plugin did not load. Check that it matches your loader.
- Yes, with the port you expect: go to 3.
3. Does voice chat have its own port?
port= in voicechat-server.properties must be a port your server really has, and not -1.
- No: do steps 1 and 2 of the fix guide. On Space-Node that means an extra allocation from the Network tab, which is free.
- Yes: go to 4.
4. Are bind_address and voice_host empty?
- No: empty them unless you know exactly why they are set. That is step 3 of the fix guide.
- Yes: go to 5.
5. Do players join through Velocity or BungeeCord?
- Yes: read the Behind Velocity or BungeeCord section of the fix guide.
- No: go to 6.
6. What does /voicechat test say?
Run /voicechat test PlayerName in game as an operator. Then pick the row that matches:
| The test says | Go to |
|---|---|
| Got a response in ... ms | Voice works. If you still hear nothing, check the icons and settings: what the plug icon and the other icons mean |
| Client not connected, for everyone | The port is not reaching the server. Back to question 3 |
| Client not connected or Request timed out, for one player only | Fix Simple Voice Chat for one player |
| Request timed out, for everyone | Voice did connect, but the pings got no answer. Rejoin and run the test again. If it keeps timing out, ask us in live chat with the voicechat lines from the console, or when self-hosting check the UDP port 24454 firewall guide |
| PlayerName does not have Simple Voice Chat installed | Back to question 1 |
| Voice chat unavailable | Back to question 2 |
Still stuck?
The fix guide explains every step above in full, with the config paths, log lines and commands. On a Space-Node Minecraft server, ask us in live chat and include your voice port and the voicechat lines from the console.
