Unable to connect to umbrel

I have umbrel installed on my linux laptop. Up until yesterday I had no problems, but today when I try to access umbrel I just receive this message ’ This site can’t be reached

matthew-thinkpad-x260.local refused to connect.’

Any ideas where to start to fix this?

maybe check via terminal ssh if the ubrel is running.

otherwise maybe you need to restart the service to get it running.
