Can't ssh into my node

Following the recommendations in here, because umbrel.local is not accessible, I’m trying to log into the node using ssh directly. I found the IP address with arp -a, but getting this error:

ssh: connect to host port 22: Connection refused

I changed the port to 2222, but still getting the same error.

FYI, never got to update it here, but the issue was a faulty OS flashing. I used another software than the recommended Balenda Etcher. Using the latter it ended up working without issue.
