Unable to access Milvus from a non-VM macOS system

Issue: If you try to access Milvus through VPN from a non-VM macOS system that uses pymilvus SDK, the connection might fail.

watsonx.data on IBM Software Hub

watsonx.data Developer edition

Symptoms

The connection might fail with the following error:
"MilvusException: (code=2, message=Fail connecting to server on your-host-name:443, illegal connection params or server unavailable)>".

Resolving the problem

Try the following to resolve the issue:

  1. Check whether the provisioned Milvus instance was deleted and a new one was created. In that case, the GRPC server and host URL might have changed.
  2. Check whether the saved certificate in the system is a GRPC certificate and not an https certificate.
  3. If step 1 and step 2 are verified as correct, add the following lines to your .pynb notebook or Python script and try again:
    1. import os
    2. os.environ["GRPC_DNS_RESOLVER"] = "native"
    For example: 
    import os
os.environ["GRPC_DNS_RESOLVER"] = "native"
connections.connect(
            alias='<db name>',
            host="<host>",
            port=443,
            secure=True,
            server_pem_path="<cert_path>",
            server_name="<host>",
            user="<username>",
            password="<password>")
