We've had a number of reports of people having difficulty connecting to, or being disconnected from, online games. Here are a few things you can try to fix the issue.
- Select a different region to play (top right corner in the lobby there is a selection box for regions). We have noticed some countries fair better with other servers outside their default region.
- We know that some firewalls are preventing "unknown" connections from within Quantum Chess. Those connections are made when a game is created. Giving permissions to Quantum Chess from the firewall might help.
- Sometimes the connection can timeout because another streaming service is running (such as a voice communication program or twitch streaming service). We usually hear this complaint with Skype. Try closing any other streaming services.
