Hi @kliknrichteam,

This would be really hard to pinpoint and would require a lot of troubleshooting. What I could suggest is to SSH and see if your fastpanel service is running on the droplet. If it’s running maybe it would be good to go over the documentation of FastPanel to see for common issues.

As a last resort, I’ll suggest contacting FastPanel’s support, I’m sure they’ve dealt with such cases before as well.
