Dashboard offline but apps not under primary domain running

[mononym]

Hello. Since this morning (update ?) my Cloudron dashboard indicates the Cloudron is offline. Reconnecting… state. All primary domain apps are not reachable but all other apps not located under the primary domain are doing fine.
What steps could I undertake to resolve this ? Thank you

Ha! Maybe I was around just the wrong moment in time. All works fine again and nothing suspicious in the logs.

Glad it worked in the end. Otherwise for reference please follow the instructions at https://docs.cloudron.io/troubleshooting/ to troubleshoot this.
