[cups] Looking for help to install CUPS

I don't think the above cupsd.conf configuration is your issue.

On the new CUPS server, confirm the web interface is working there with the following command :
   curl http://mycups.com:631

I would recommend keeping a cups.sock line for localhost cups command-line commands. From memory I had to use ' ServerName for upgrade redirection from http to https to not replace the server hostname with an IP address (maybe also needed 'HostNameLookups On'). Anyway, this is what I'm using:

Port 631
Listen /run/cups/cups.sock
ServerAlias *
ServerName mycups.com
HostNameLookups On

A web proxy is most likely returning HTTP status 502 bad gateway and chances are it can't connect to your news CUPS server. I have no idea of the network topology and setup, maybe the old CUPS server was being bypassed by the web proxy.
