I've see a lot of message in the dex logs like the following:

2025/07/01 07:19:22 http2: server: error reading preface from client 10.128.58.26:36894: read tcp 10.128.20.22:9443->10.128.58.26:36894: read: connection reset by peer

after looking for the ips of the client, I saw it was Openshift's ingress controller which runs ha proxy that tries to reach dex. because of the frequency of the requests, it looks like a health check.

I suspect that ha proxy doesn't support running health check using http2.

This issue doesn't affect users. It's still possible to login to the Konflux UI.
