Thanks for reporting it, I will take a look.

I think this is an issue with our HTTP2 support. The related problem is this one #742. We only support golang.org/x/net to version 0.21 and there were some breaking changes in the API. I see that longhorn mentioned here is on version 0.22.

I'll prioritize fixing this.

thanking for replying, the longhorn version is 1.5.4, and the version of golang.org/x/net is v0.20.0 in go.mod in that branch, ref https://github.com/longhorn/longhorn-manager/blob/v1.5.4/go.mod https://github.com/longhorn/longhorn-instance-manager/blob/v1.5.4/go.mod https://github.com/longhorn/longhorn-engine/blob/v1.5.4/go.mod

Thanks for the info! I did find one more issue and that's also in the PR. Once it's merged in main, I'll backport it and we'll make a new 1.4 release.
