hi @AnnTade !!
Welcome to our community !!
The python client v4 introduces the GRPC connection. So in order to use it, you need to make sure you server is a recent version (1.25+ should be fine) and has the GRPC port exposed.
Now, if your cluster is under a SSL/TLS endpoint, you need to make sure that both grpc and http endpoints are secure in the client.
Here you can customize your connection. So let’s say you expose http and grpc on different ports, or different domains, etc:
Let me know if that helps!
