Node doesn't start: Error: System service failed

I get the following error message from my node: “Error: System service failed” The node doesn’t start. It ran fine, but the bitcoin node wouldn’t start, then I restarted it. Haven’t upgraded the software for a while. Any clues how to fix it? I can see it in my wlan, though.

What are you running UmbrelOS on?

And I assume you have seen troubleshooting guide for this?
