I am using MX-Linux as my main OS. Unfortunately, I cannot make or answer a call over Facebook Messenger web on any browser. I tried doing that on google chrome, firefox and Opera. However, I got the same result. I also tried removing all extensions but eventually could not achieve what I wanted. I also tried doing that in firefox troubleshooting mode. Nevertheless, I was disappointed too in this case.
Someone might ask me to have a look at firewall rules. So, here, I am pasting my iptables ruleset. And for clarification, I don't know which rule might be causing the trouble.

I guess it was due to being an electron app (using chrome extension).
Can anyone help me with this? Any help would be highly appreciated.
