Issue connecting with gRPC APIs

@Erebe I am getting grpc connecting issue many times.
Do you have any idea?

"status: Internal, message: \"protocol error: received message with invalid compression flag: 60 (valid flags are 0 and 1) while receiving response with status: 502 Bad Gateway\", details: [], metadata: MetadataMap { headers: {} }"

here is NGINX error log
