Hi Panoramix,
this can have several reasons.

🔸 Cache & Cookies Overload – Old data can interfere with game connections.
Clear your browser's cache and website data - make sure to select "All" (not only the last 24 hours). 

🔸 Extensions Interfering – Some browser extensions (like ad blockers or VPNs) might block online games.

🔸 Outdated Browser – Running an older version might cause compatibility issues.
Update your browser to the latest version

🔸 Firewall/Antivirus Restrictions – Sometimes, security settings prevent access.
If you changed your firewall settings recently, change them back to as they were.

You can also try using a different browser and see whether you can connect to the games.

If none of this resolves your problem, contact FlyOrDie's technical support and allow them a few days to get back to you.
