Test if the media URL is correct in OFFLINE upgrade

SM 4.2 setting up fist offline upgrade for zLinux servers. then X_86 servers.

Following Documentation for creating the distribution, Profile, Autoyast using a supplied XML file from SUSE site.
when I tired upgrade I get message on server no media found.
I tried entering the URL on web Browsers it fails to open a site.
I noticed that the URL has /ks/dist added in the path.
Is there a way to test URL used prior to trying upgrade?

Thanks for all your help Bryan
