@CarnaViire given the error message this looks like an area-System.Net.Http or test infra issue?

[eiriktsarpalis]

@dotnet/ncl ☝️

[CarnaViire]

I've found that the test was introduced by @MihaZupan in #79386
It doesn't seem like an infra issue, as the connection is to localhost. Could it be test issue @MihaZupan -- any thoughts?
Interestingly, I don't see such failures in Kusto...

[MihaZupan]

Seems like an infra/environment issue to me, I don't think there's anything special with the test up to the point where the loopback connection is made. If we haven't seen more failures for it I'd ignore it.

[eiriktsarpalis]

Seems that we could close this for now.
