Unable to connect to players with ice error

The error is
20:18:12.724 [Thread-4] DEBUG c.f.i.i.Peer - Error while reading from local FA as peer (probably disconnecting from peer) Kampfkartoffel(131487)

Which just keeps spamming

I have my ports open(DMZ) and my firewall disabled.
I tried reinstalling faf and deleting the faf folder but didn't help.
It also causes the windows dns process to flare up to 100% + the client on my ryzen 2600.

Forwarding ports is unnecessary.
The error you posted is normal.

The main issue is this:

java.util.concurrent.CancellationException: null

This means your operating system or antivirus is closing the socket and not telling the adapter why.
This only occurs on less than a few percent of devices. I spent a lot of time debugging that and sadly didn't find a solution, the issue lies somewhere within proprietary code of your operating system manufacturer.

Try the options suggested in https://wiki.faforever.com/index.php?title=Connection_issues_and_solutions#Unable_to_connect_to_someone
in the order they're listed in. Each is more likely to fix the issue, e.g. VPN worked on one of my machines when I had that issue.
