I’m running Cloudron on a VPS and I can no longer access the Cloudron dashboard.

The dashboard shows:
“This app is currently not responding. Please try refreshing the page in a few minutes.”

From the server terminal, it looks like there may be an issue with the firewall/kernel configuration. The services box and cloudron-firewall do not seem to start correctly.

What I already tried:

• Full server reboot
• Manual restart of Cloudron services from terminal
• Generated a Cloudron support login with cloudron-support --owner-login

Important constraint:
Reinstalling the server is not an option because I need to keep the existing data and apps.

Goal:
I need help diagnosing the firewall/kernel issue and restoring access to the Cloudron dashboard without data loss.

Could someone tell me which logs or commands I should check next?

Thanks.
