Way to test this, using the model from https://github.com/ansys/pymapdl/issues/2479 connecting to v25.1.0 docker image.

Then run:

python  compute_for_multiple_mesh_size_wb.py > log.log 2>&1

and then:

$ tail -n 600 -f log.log | grep retrying

I saw this:

<_InactiveRpcError of RPC that terminated with:
        status = StatusCode.UNAVAILABLE
        details = "failed to connect to all addresses; last error: UNAVAILABLE: ipv4:127.0.0.1:50062: FD shutdown"
        debug_error_string = "UNKNOWN:Error received from peer  {created_time:"2024-08-08T22:33:17.948629+02:00", grpc_status:14, grpc_message:"failed to connect to all addresses; last error: UNAVAILABLE: ipv4:127.0.0.1:50062: FD shutdown"}"
