grpc_health_probe timeout with dotnet GRPC API - asp.net-core

Question

I'm running a dotnet GRPC API (recipients-api) and I want to use grpcui to test it. Both services are been declared on a docker-compose file. I'm declaring grpcui as a dependant service of recipients-api, and as I need it to be fully available before grpcui can run, I'm also using a health probe to ensure it's alive. The problem is that it seems like recipients-api entry point is not been run, it's like the process were stuck waiting for the health check to be sucessfull before hiting the container entrypoint, so it alsways throws a timeout. Any clues?
Here is my docker-compose file:
