as you can see in the log, it is trying to fetch the correct file (APT is able to figure it out ), and the message indicates a connection error. Can you ping the IP/download the file manually?
Thank you for the help. I can ping the url from the server I can ping google.com so seems DNS is working (using 126.96.36.199). When it tries to get that file I see it flash 10min to download, but goes away.
