Avast blocking voice chat in online games

Hey forums,

Today I moved my computer to a different router, and then suddenly avast free antivirus no longer allows voice chat.
I didn’t mess with any settings or anything, so maybe some cached data was causing the issue. But I uninstalled/reinstalled and am still receiving the same issue.
Do I need to add the game .exe files to the exclusions list to fix the problem? Or is it a setting that might’ve changed?

Any help would be appreciated.
Thanks,

In addition to that, it is also blocking access to game servers in other games.

It is more likely the new router is causing the problems.
Check the settings.

I thought that, but when I uninstall avast, everything works like it had in the past. And then a reinstallation just renewed the same issue.

What exact version of avast ?
