Mirotalk - Participants can't see each other 2

[ekevu123]

The issue that Mirotalk video chat participants can't see each other has been discussed before. It has been suggested to switch ports to 25000, however, this doesn't solve the issue for me. I have installed the newest version, and did try to re-install Mirotalk, just in case.

Switching to port 25000 is a good suggestion, but if that didn’t fix it, you might also try checking firewall/UDP settings or NAT traversal — MiroTalk’s video streams often get blocked by network rules. If you're open to it, I can help you test which ports or configs might work in your specific setup.

[ekevu123]

Sure! I don't have any specific setup, though. Just a Ubuntu server on Netcup and then Cloudron installed.

I have the same set-up as you, Netcup + Cloudron and MiroTalk works fine. So you're saying this didn't help? If not, then can you describe a bit more what you see? Do you see wheel spinning as if the participant were trying to connect, or you don't see participants trying to enter the room at all?

If I am not mistaken, a new Mirotalk installation on Cloudron sets the port automatically to 25000. I have verified that I have that set up once more.

Oddly, I have just tried it once more, and now it works. Maybe because of a recent app update, I am not sure.

Not sure why, but in the Cloudron setup, it only works when the port range starts from 25000.

In theory, it should work with any port range, as long as the selected ports are not already in use by another application and are not blocked by your firewall or ISP.

Thank you for explaining! If it happens next time again, I will look through port usage on the server.

Hello @ekevu123 and @mirotalk-57bab571
I have figured out what the issue is with changing ports.
An app update will be available soon that fixes this issue.

Good!

@james This issue is back

Hello @avatar1024
I was unable to reproduce this issue.
Changed the ports from 25000 to 30000 and tested with my desktop and mobile phone with no issues.

[ekevu123]

It has worked again now after changing the port and restarting the app. Does it need to be any port between 25000 and 30000?

[james]

Hello @ekevu123
No. I've also just tested with port 5000.
But the ports need to be free since 100 ports will be used.
So if you set the port to 5000, from port 5000 to port 5100 will be used.
If a port in that range is used by another application, the mirotalk application will have issues.

You can try to enable the WebRtcServer feature by adding the following to your env file:

SFU_SERVER=true

Then, restart your instance.

How it works:

• MiroTalk spawns one Worker per CPU core by default.
• Each Worker runs its own WebRtcServer on a dedicated port.
• Ports are assigned sequentially starting from a base port (eg: 25000).
• This approach keeps port management simple: you only need to open as many ports as you have Workers.

Optional: You can manually set the number of Workers using:

SFU_NUM_WORKERS=4

Example:
A server with 4 CPU cores (or 4 Workers) and a base port of 25000 will use the following ports:

25000, 25001, 25002, 25003

You only need to open these 4 ports on your firewall.
