I have a federated server (flower framework) running in a docker container in the raspberry pi device in the same network as the client (My laptop). The client is not able to establish a connection with the server.

Raspberry pi host ip address: 192.168.0.104 Docker container ip address: 170.17.0.2

I enabled port forwarding for the docker container from 8080 to 8000. When I try to connect the client to the server’s 192.168.0.104:8000 address and port. I get the error

status = StatusCode.UNAVAILABLE details = "failed to connect to all addresses; last error: UNAVAILABLE: ipv4:192.168.0.104:8000: WSA Error" debug_error_string = "UNKNOWN:failed to connect to all addresses; last error: UNAVAILABLE: ipv4:192.168.0.104:8000: WSA Error {created_time:"2023-08-19T13:55:0 7.018340428+00:00", grpc_status:14}"

I have disabled the firewall in the client (my laptop).

I searched whether raspberry pi has any firewall blocking the connection, but I haven’t found any solid information. Am I missing anything, sharing any information or direction in which I must head will be appreciated.

Thank you.

  • [Solved] Need to pass network parameter in docker run ```--network="host"``` The container will share the network stack with the docker host.

    `--network=host` generally disables Docker's networking layer, and it's almost never necessary. Right now you've only loosely described the application setup, but without a lot of details; can you further [edit] the question to include a [mcve]? – David Maze Aug 19 '23 at 18:17
