Root Cause

HTTP/2 framing violation between client and server. Often caused by an intermediate proxy (nginx/Envoy) that doesn't support gRPC, or a mismatched h2c/TLS configuration.

generic

中文

客户端与服务端之间的 HTTP/2 帧协议违规。常见于中间代理（nginx/Envoy）不支持 gRPC，或 h2c/TLS 配置不一致。

Workarounds

  1. 85% success 
    Configure the proxy for gRPC (HTTP/2 end-to-end). For nginx:
location /pb.UserService/ {
  grpc_pass grpc://backend:50051;
  grpc_read_timeout 300s;
}
  2. 90% success 
    Bypass the proxy entirely to isolate: dial the gRPC server directly from the client host and confirm the call succeeds.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    PROTOCOL_ERROR is a framing issue, not a stream-count limit.

  2. 80% fail

    Keepalives don't fix malformed HTTP/2 frames; aggressive pings may trigger GOAWAY from servers.
