Hello. I have a user in one of our smaller offices that was suddenly unable to use the normal license host name to connect to the license server. It occur a couple of days ago. People in other offices are fine. We can ping the license server host. When I put the name and port number in the web browser as http://esrilicenseserver01:27004 it does not return a 404 error. Entering the host name return the error "...Invalid host name". When I use the port@ip format, it works. Just wondering why the host name is suddenly not working. Not sure if it's an application error or a network error.
