Failed to connect to PRIME GRPC server

I am getting the following error.

Failed to connect to PRIME GRPC server
Traceback (most recent call last):

File ~.conda\envs\myenv\Lib\site-packages\ansys\meshing\prime\internals\grpc_communicator.py:86 in init

The above exception was the direct cause of the following exception:

ConnectionError: Failed to connect to Server in given timeout of 20.0 secs

Please let me know how to resolve it

@ragulselvaraj20 depending on your setup regarding licensing we have seen issues with the timeout not being sufficiently long to allow for a license to be acquired. Please could you try increasing the timeout to say 60 secs to verify that you can launch the server?

import ansys.meshing.prime as prime
prime_client = prime.launch_prime(timeout=60)

I hope this helps! Thanks

Hello, it shows me a different error even after adjusting the timeout to 60 seconds.

Hi @som1197 , thanks for opening a separate discussion on this #814 as this is a different issue.
