Cannot connect to Couch Potato

[troymeredith]

Dear All,
 
I've had Couch Potato on my docker for a good few years now, however in the last couple of months I have been unable to connect to it.
 
I get a "This site can't be reached" message along with:
 
ERR_CONNECTION_REFUSED
 
I've been using Chrome and Safari, same result.
 
Any thoughts as to what I can do to rectify and get connected to CP again?

 

Diagnostics attached.
 
Many thanks in advance

Instead  of diagnostics, what you need to do is this:  (And ideally post in the support thread for the app in question)
