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

2024/03/27 08:52:47 [error] 2508#2508: *13763736 no connection data found for keepalive http2 connection while sending request to upstream, client:, server:, request: "POST /voice_service.VoiceService/voice_gen_by_video HTTP/2.0", upstream: "grpc://", host: ""
