I'm trying to connect to a server from my client using gRPC, but connection always fails only on my pc(macbook pro). My teammate tried with the exact same code, and it works perfectly fine. The following is the error messages from each client and server. We are using protobuf 3, python 3.9. Can anyone give me some hint? Thank You.
Client Error Message
