Root Cause

The client requested a compression algorithm that the server does not support.

中文

客户端请求了服务器不支持的压缩算法。

Workarounds

  1. 90% success Change the client to use gzip compression. Example: `channel = grpc.insecure_channel('target', options=[('grpc.default_compression_algorithm', grpc.Compression.Gzip)])` 
    Change the client to use gzip compression. Example: `channel = grpc.insecure_channel('target', options=[('grpc.default_compression_algorithm', grpc.Compression.Gzip)])`
  2. 70% success If using custom compression, register it on both sides via `grpc.Compression` API.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    gRPC does not support deflate; it only supports gzip, identity, and optionally snappy or zstd.

  2. 70% fail

    The server will still reject it because the algorithm is not in its supported list.

  3. 95% fail

    gRPC does not negotiate compression; mismatch causes immediate failure.
