It’s very important that the RTC port range you configure is:
Not already in use by any other application
Not blocked by your firewall or ISP
For testing purposes, you can enable the SFU server mode by editing the env file (via the File Manager) and setting:
SFU_SERVER=true
After saving the change, restart the service and check if anything improves.
In this mode, MiroTalk SFU uses fewer ports while maintaining nearly the same functionality.

Note: MiroTalk SFU can handle approximately 100 concurrent participants per CPU core, depending on your hardware and network conditions.
