I have problems to connect to the license server outside of our local network:

This is the setup:

• The license server is hosted on a machine in place A with its own local network
• The license for the server was generated with the local hostname of the machine (myLocalHostname) and its hostid
• To access the license server from outisde of place A I have forwared the ports for ansyslmd (static configured port 50725), lmgrd (1055) and the ANSYSLI_PORT (2325) in the router of place A (and of course in the Windows firewall of the machine)
• Also I have setup a dynDNS to get the public IP of the router of place A (myDynDNS.de)
• On my client machine I have setup the license server (in Licensing Settings 2023 R2) with port 1055 and with Server 1 = myDynDNS.de

This is what happens:

A) I access the license from within the local network of place A but with the public ip:

• Menu "License servers": Test-Button results in a green checkmark
• Menu "Feat in use" log:

1055@myDynDNS.de

License server status: 1055@myLocalHostname
    License file(s) on myLocalHostname: C:\Program Files\ANSYS Inc\Shared Files\Licensing\license_files\ansyslmd.lic:
myLocalHostname: license server UP (MASTER) v11.19.0
Vendor daemon status (on myLocalHostname):
  ansyslmd: UP v11.19.0
Feature usage info: 

So everything works fine in the local network.

B) I access the license from place B (outside of place As local network) with the public ip:

• Menu "License servers": Test-Button results in a green checkmark (so this still works)
• Menu "Feat in use" log:

1055@myDynDNS.de

License server status: 1055@myLocalHostname
    License file(s) on myLocalHostname: 1055@myDynDNS.de:
lmgrd is not running: Cannot connect to license server system. (-15,10032)

This time it doesn't work. I am wondering though why the marked line still shows "1055@myLocalHostname" and not "1055@myDynDNS.de". It seems like "lmutil" still tries to search for the local hostname and not for the public ip.

Any idea how to solve that problem?

Check the SERVER line in the license file.
Stop the ANSYS License Manager
Change it from local hostname to 127.0.0.1 or localhost.

SERVER 127.0.0.1 hostid  1055

Restart the License Manager

Thank you very much that finally solved it. 127.0.0.1 didn't work but localhost did the trick.
