Constant errors connecting to unavailable server

Several weeks ago my Macbook Pro (Catalina) started popping up the following "There was a problem connecting to the server "xxxxx.xxxxx.xxxx.com". The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."

This is a valid server, and I am able to connect to it fine while at my work office. When away from work office it continually tries to connect (every hour or less). When it occurs, there are 11 popup error messages.

If I change networks, i.e. wifi access point A to access point B, errors popup immediately.

I've searched all over and tried dozens of 'fixes' with no luck, including:

• Delete ~/Library/Caches
• Remove network shares from User Login items
• add "local" to each network device DNS search
• remove matching entries from KeyChain
• Remove all Alias files on drive
• Reconnect to server (which is at office), Eject properly, leave office... when away from office issue returns

I created a 2nd ADMIN account. Logging into that account I do NOT have the issue. It is limited to primary user account.

I've searched for the server name on drive and removed any references to it in the content of local files.

Used CleanMyMac to remove all "Junk" files

Suggestions?
