Nextcloud backup addon error

I am trying to configure the Nextcloud Backup addon but I am unable to get it to connect to my Nextcloud instance.

I get the message:

Can't connect to Nextcloud (Error: getaddrinfo ENOTFOUND https) !

I have configured an app password for HA in Nextcloud

You solve the problem?

No I didn’t. And now I have a bigger problem which is nextcloud is down all together due to the fact that I mistakenly try to upgrade to a major release which wasn’t the next one to go to. When and if I get that resolved I will go back to trying to get the Home Assistant back up add on to work
