Avast Firewall issues

So ever since i got Avast Internet Security i have had issues with Teamspeak staying connected and would not be able to reconnect until i shut off TS3 and restarted it, at first i just though it was an issue with the server but i was always the only one dropping, i ignored it for the longest time and then began to get annoyed because it was happening more frequently. I looked it up online and i saw some people saying it could be my router, so i began playing around with the settings but could never figure it out, i was about to call my ISP and ask them about it when i realized that i now had a firewall with Avast, i tested it by switching my firewall off and POOF i reconnected instantly. I tried to figure out what setting in the firewall could do this, i looked at the application rules and firewall settings but i am unable to pinpoint what is causing this

Avast Version -
12.1.22.72 (build 12.1.3076.11)

Any help would be greatly appreciated,
Thank you.

Update to the latest version (12.2.2276): https://forum.avast.com/index.php?topic=189131.0

i have been having this issue for like a year now so i have had this issue through many updates, though i did think i had the latest, i doubt this will fix it but i will indeed update and see if it makes any difference

OK, report back.

I now have 12.2.2276 (build 12.2.3126.2)

As i suspected, it once again started to do it, and once again as soon as i turn it off i was able to connect, so the build version was not the issue. It must be a configuration somewhere in the firewall
