Discord issue while VPN is on

Hi!

I have a weird issue which I mapped so far to Avast activity. I have Avast Premium Security and before this week Discord was working fine with it.
For discord to work I need to run VPN because ISP blocking Discord VoIP. I run ExpressVPN and this mix was working fine until this week.

This week as soon as I engage VPN discord stops updating any channels like it’s not getting any internet connection. As soon as I disable Avast protection and restart Discord it starts working with VPN on. I’ve ruled out firewall, tried to disengage only firewall but it did not help.

Maybe anyone has idea where I can continue troubleshooting?
