Does this still work for you?

I have a similar small project, and at some point recently, I started getting errors like:

rpc error: code = Unavailable desc = transport is closing

from the old process that should be gracefully stopping, instead of valid responses. I decided to use your project as an alternative to see if it helped me find where the problem is coming from, but my application gets the same error, when I use your grace/grpc wrapper.

I am wondering if you have checked recently, on recent versions of grpc, and if you might be having similar issues....
