In my case, I also did open port 8443 from WAN to my unifi controller. I am running on ETH1 Network type with static IP. I had this port open while testing various approaches. Closed it, once I got unifi.ui.com working. This port should be used for UI access only and don't think unifi servers use it for validation. can you verify your firewall is not blocking outbound traffic for this container?

I recently migrated to the new UniFi Controller container and also faced issues getting cloud access to work after the migration. After numerous attempts, here’s the process that finally worked for me: Set-up fresh controller (don't recover from backup just yet) Sign in with your Unifi account and login Settings -> Backups -> Restore -> Restore from backup Settings -> Advanced -> Disable "Remote Management" -> Remove Re-enable "Remote Management" and sign in with your credentials + MFA 💡 Note: Steps 1 and 2 might be unnecessary if you restore from backup during the initial setup. However, I didn’t want to experiment further after finally resolving the issue. A big shout-out to the team behind the UniFi-Controller-Reborn Docker! The installation process was smooth and hassle-free. I initially tried using the LinuxServer container but had a frustrating experience—performance was painfully slow, and I lost a day troubleshooting. Switching to UniFi-Controller-Reborn was a game-changer. Thank you for making this container available!
