I was trying to host a sample gRPC code in Huggingface Spaces and when i am trying to call the server via the gRPC client, i am getting the error message as Connection Refused.
This is the space - [GRPC Testing - a Hugging Face Space by Bleak](https://huggingface.co/spaces/Bleak/gRPC-Testing)
Below is the detailed error message which i am getting when i am trying to connect to the Spaces via gRPC -

In the dockerfile, i have also correctly provided the Port (7860). Can i please get some guidance about where am i going wrong ?

Is gRPC not supported in HuggingFace Spaces ?

The settings don’t seem to be wrong.
It may be a library that is implicitly prohibited by Spaces. There are quite a few like that…
