For some reason I'm no longer able to connect to sab sonarr or couch

Sab shows nothing
Sonarr shows null error
And couch shows an java message error (attached)

What happened?

Turns out my main IP address had changed
Updated it and all is fine again
Get yourself a DDNS address.

Would stop this sort of thing happening.
