Wrong SERVER hostname used or contains a typo

Version 1

    If  you chose a server hostname that can't be resolved by the license   server, a message like the following will appear in the license server   debug log file:


    16:52:11 (lmgrd) "<your_hostname>": Not a valid server hostname, exiting.
    16:52:11 (lmgrd) Valid license server system hosts are: "put_server_name_here"
    16:52:11 (lmgrd) Using license file "C:\license_files\license.dat"


    You  may have chosen a hostname that resolves but is not the actual   hostname of the license server. In that case, the license server will   start without errors but your clients will fail to get a license. The   errors on the client will most likely not indicate a server hostname   problem so be sure to get the correct name for your license server.


    It's  helpful to run 'ipconfig /all' on Windows and the 'hostname'  command  on Unix/Linux to verify the server's hostname. It's also a good  idea to  'nslookup <hostname>' to verify that the IP address that  is  returned is what you expect. Often, the hostname resolution differs   between the network lookup and the local host lookup.
