It can be a malformed management API URL. In the browser's development tools > console or network tabs you should see the error as well. can you share it for us? you can mask the domain with something like netbird.example.com

You are right, it is related to nginx. I want to find a time to validate and test it out. The issue only happens when there is a large period of time without new updates and nginx might not be forwarding the keepalive messages between the peer and the signal server. If possible please share your case in the https://github.com/netbirdio/netbird/issues/651 ticket as well.

I loved the work you've done here @jimrummy101. I will be happy to answer or support if you have any questions or issues with NetBird
