October 7, 20223 yr Cant get the backup working, always get this error message. "Unable to connect to backup.unraid.net:22" any ideas what to try? So far i've tried updating, log out and in from my servers, restarting in terminal, but it always returns the same error when i press activate. tower-diagnostics-20221007-2318.zip
October 7, 20223 yr This means that some sort of firewall on your network is preventing the server from connecting to backup.unraid.net on port 22. You'll need to unblock that on your firewall in order to use the automated flash backup feature.

I do not have any rules that reject outbound ssh connections, or is it inbound? if i try ssh backup.unraid.net in terminal i get permission denied, not time-out Do i have to open port 22 inbound?

No, no inbound ports required. Please open a web terminal and run these two commands: timeout 5 bash -c "</dev/tcp/backup.unraid.net/22" echo $?

October 13, 20223 yr I am pretty confused by the fact that this works: ssh backup.unraid.net and this doesn't: timeout 5 bash -c "</dev/tcp/backup.unraid.net/22" echo $? The only thing I can think of is that the bash command isn't using ssh and maybe your firewall is blocking it because it expects port 22 traffic to be ssh. What firewall are you using, and can you check the logs to see what outgoing traffic is being blocked when you type that bash command?
January 30, 20233 yr I have the same issue. Would it help if I posted the diagnostics? Quote root@server:~# timeout 5 bash -c "</dev/tcp/backup.unraid.net/22" echo $? 124 root@server:~# ssh backup.unraid.net [email protected]: Permission denied (publickey). root@server:~# The above is my server response on terminal
