Unable to create or join games

Seem to have an issue with creating and joining games since the updated client has come out. Have this error:

@grindalf1 based on this list of common errors in the FAQ (https://forum.faforever.com/topic/4256/solutions-for-common-errors-with-the-faf-client-launcher-or-supreme-commander) yours seem to be case 1.

Problem:
RuntimeException: javax.net.ssl.SSLException: Tag mismatch!

Solution:
The client is unable to establish a secure connection to the content server for downloading the game files.

  • Disable security software for testing purpose
  • Check firewall settings, if it blocks anything related to secure connection/FAF Launcher

@amygdala cool thanks, will give it a go 🙂

Sadly, no joy. Any other suggestions?

Got it working, turns out it was an issue with my connection. Feel like a moron, but thanks for helping 🙂
