When accessed via LAN, Server doesn't find databases

[MSPJ]

I'm having something odd happening.  I'm running FMS18 on a server on my LAN. When I run admin console on that machine, everything is as it should be.  SSL certificate is installed, valid license, expected databases are open.

When I access via another computer on the LAN, using IP address:16000/admin-console, I am able to login and it shows the server is running BUT no databases are there, license shows as expired and there is no installed SSL certificate. In the past, I've had issues where firewall software prevented accessing the console over my LAN - but I've never had a situation where I could log into the console from another machine, but server reported all this incorrect information.

I can remote desktop into the server machine from the other computer, and run the console locally (port 16001) - all is good.  But putting the same IP address into a browser on that other computer, I get this weird result.  This started happening quite recently, and no doubt there have been windows updates since then.  I'm just not sure where to look.  

Thanks for any suggestions.

If you have an SSL cert installed you should always address the server by the name on the cert and never use the IP address.

That wouldn't explain the issue you are describing but it prevents many other issues.  What do you get when you use the DNS name?
