Umbrel was working perfectly until the end of last week when I couldn’t open bitcoin core. I restarted the server to see if it would come back and now it won’t open any app. The message that appears is:
Unable to connect
Firefox could not establish a connection with the server umbrel.local:2100
- The site could be temporarily unavailable or too busy. Try again in a few moments.
- If you are unable to load any pages, check your computer’s network connection.
- If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.
- If you are trying to load a local network page, please check that Firefox has been granted Local Network permissions in the macOS Privacy & Security settings.
