Hi. I'm a beginner at Ansys. I want to use anansys fluid. There is a license server on another PC, another PC, and that server is working well. However, when I run workbench, the error message box as below appears.

"Connection timed out while reading data.
The application has stopped waiting for a reply.
The license server may be experiencing a high demand or a temporary outage. Try again later."

It was judged that it was not a normal situation for such a message to occur, and issues on the same problems were identified.

1. The PC that is causing the problem is different that it is not a server PC, and I couldn't find ansysli_server.exe and lmgrd.exe in programs that I could add to the exception of firewall. So I tried adding ansysliZ_client.exe just in case, but it didn't work out.

2. As you can see in the picture below, the license server setting test result is normal. Also, I received a reply from the license server management team that the server is running normally.

3. I also tried changing the settings of ansyslmd. There is content about SERVER, but there is no content about ANSYSLI_SERVERS, so I couldn't change the settings.

4. I also checked the comments below and tried to change the setting variable, but I couldn't find ANSYSLI_TIMEOUT_TCP.

------------------

if anyone facing ANSYS license Server timeout issues. 

Add the below environment Variable in your account

Name : ANSYSLI_TIMEOUT_TCP

 Value : 300

It will resolve your issue.

5. In this situation, when I turn on the workbench, the following error message occurs twice. Is this a normal situation?

       

 

Maybe it's the wrong question because I don't have enough knowledge about licenses, but I have questions.
Could it be a problem with the license server in this situation?
For example, could it be a problem because the port is not opened, or could it be a problem because it is not designated as a license-enabled IP?
How can I solve this problem?

I’ll add one more thing. I don’t know if it’s normal because it’s not a server PC, but I couldn’t find any services related to ansys in services and applications. Is this an installation error problem…?

I'm having a similar issue, did you ever figure this out?
