Looking at the logs, it seems like the connection was reset for some reason:

07:51:22.179 [armeria-common-worker-epoll-3-4] WARN  c.l.a.i.c.AbstractHttp2ConnectionHandler - [id: 0xfa43be94, L:/127.0.0.1:34782 - R:127.0.0.1/127.0.0.1:43087] HTTP/2 connection error:

To be honest, I don't think there's much that can be done for this case other than marking as flaky, or removing it.

Given that this test isn't really failing often compared to other tests, let me just monitor this case and remove if needed
