All is well.  Connection is going fine.  I resolved the problem using your suggestions and realizing one critical error on my part.  We have Xfinity comcast for our carrier but we have a security part of the network  and a non-security Xfinity connection.  The computer I was using automatically loads on to the non-secure connection but the Mobile Sheets app wanted to be on a secure connection.  As soon as I switched to the secure site, the Mobile Sheets loaded right up.
Thanks for all you help.
