WebSocket disconnects about every minute

Hi, I am using mediasoup-demo, While chatting with someone WebSocket disconnects and then reconnects about every 1-2 minute. I made telnet to 4443 port of mediasoup telnet also gets lost when this disconnection occurs. And it happens on all participants of chat at once. Please help to resolve this issue.

mediasoup is not listening in port 4443. Really, it’s not mediasoup.

Not sure if you are using your server or using the demo online.

I have changed default port. I have found the reason. SeLinux was blocking the socket connection every 90 seconds.

Thanks again.
