We have current license server is live on a network that is not accessible by our HPC cluster. Can we know how we can get a file based license from the existing licensing and use it on our HPC cluster which has Ansys Fluent 2021R1 configured and we are using RHEL 8.5 . Can we also know if we can use 2020 's version of ansys fluent license server for 2021 R1 on HPC?

I do not believe this is a licensing issue, however if you want to switch where your license exists, You can have your License Administrator or Ansys Support Coordinator rehost the license key to another machine. You can also reach out to your ANSYS Account Manager.

The Error in the pic you posted look to be prerequiites missing or incompatible:

i have tried conneting to the license server using telnwt command. After i do this and run fluent i am getting the following error. Can i know what should be done to run fluent by connecting to the license server from other machine

[George Karnos]

Check the firewall.

On the license server machine, verify that the following are added to exceptions:

lmgrd.exe
ansyslmd.exe
ansysli_server.exe

This error is usually due to the ansyslmd being bloecked.

[Aneela Banda]

when i do telnet its getting connected right

[George Karnos]

Through port 1055 it is.

ansyslmd uses a different port.

[Aneela Banda]

ok by adding those exceptions in the machine where license server is present and running the fluent in my machine works right? or should i have to add any other configuration on my system?

[George Karnos]

Yes, it should run.
That error usually mean ansyslmd is being blocked on the license server.
