connect to an existing session (from_connection) - error with IP and port

[EC-SIM]

Hello,

I am trying to connect to a running Fluent session (2025R2). Therefore I have started a web server in Fluent and received the following message in the Fluent terminal:

Web server started at {'http://xx.xx.xx.xx:5000'}
(Note - Some of the URLs might not connect depending on the network setup.)

As a second step I want to connect to the Fluent session in pyFluent using the following code:

solver_connected = pyfluent.Solver.from_connection(ip='http://xx.xx.xx.xx:5000', port=5000)

With that I got the error massage:

result = sock.connect_ex((ip, port))
socket.gaierror: [Errno -2] Name or service not known

As this did not work, I have tried the second way:

1. I have started a GRPC server in the Fluent console by:
   start-grpc-server
   Enter filename which will store the server information ["server_info-4123854.txt"]
   Information: The server has started and is running.

2. I tried to connect to the session in pyFluent:
   solver_session = pyfluent.connect_to_fluent(server_info_file_name=server)

Here I got the error message:

ValueError: Connecting to remote Fluent instances is not allowed. Set 'allow_remote_host=True' to connect to remote hosts.

Can someone help me with connectiong to a running Fluent session?

Could you check the ip address written out in server_info-4123854.txt? If Fluent is being run on the local machine, either the localhost or 127.0.0.1 should be written out in that file. If some other ip address is written out, please set the environment variable REMOTING_SERVER_ADDRESS=127.0.0.1 before starting the Fluent session. That will resolve the error "ValueError: Connecting to remote Fluent instances is not allowed. Set 'allow_remote_host=True' to connect to remote hosts.".

Thank you very much for this top. It helped me get pyFluent running.
