Grpc.Core.RpcException

Message=Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionExact while unable to establish HTTP/2 connection.", DebugException="System.Net.Http.HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionExact while unable to establish HTTP/2 connection.")

此异常最初是在此调用堆栈中引发的:
System.Net.Http.HttpConnectionPool.ThrowGetVersionException(System.Net.Http.HttpRequestMessage, int, System.Exception)
System.Net.Http.HttpConnectionPool.SendWithVersionDetectionAndRetryAsync(System.Net.Http.HttpRequestMessage, bool, bool, System.Threading.CancellationToken)

System.Net.Http.HttpMessageInvoker.SendAsync.__SendAsyncWithTelemetry|6_0(System.Net.Http.HttpMessageHandler, System.Net.Http.HttpRequestMessage, System.Threading.CancellationToken)
Grpc.Net.Client.Internal.GrpcCall<TRequest, TResponse>.RunCall(System.Net.Http.HttpRequestMessage, System.TimeSpan?)

内部异常 1:
HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionExact while unable to establish HTTP/2 connection.

The failure occurs in Qdrant.Client.QdrantClient.ListCollectionsAsync, called from the user's Form1.CreateClientWithRetry at line 85; start by reproducing that call. Review the SDK's gRPC connection path alongside the Docker and Ubuntu server setup for the reported HTTP/2 exception. Done means identifying a reproducible compatibility or configuration cause and verifying that ListCollectionsAsync succeeds.
