I have created a google cloud load balancer: configuration.
The backend is an unmanaged instance group. For example, it consists of one VM. The gRPC service is deployed on the VM (port 443). gRPC health checks are successful. But the gRPC client cannot connect to the service. I can't find a solution to this problem.
The last thing I found in the documentation:
If you use HTTP/2, you must use TLS. HTTP/2 without encryption is not supported.
Could this be a solution and I just need to secure the gRPC connection with SSL/TLS?
You need to enable TLS on the Load Balancer and also between the Load balancer and your backend VM
