Server Failed Healthchecks

OS: Ubuntu LTS
Haproxy: 2.8.5-1ppa1~jammy 2023/12/09

Hi all,

I am having a bit of an issue I don’t know how to troubleshoot.
I have a haproxy cluster where there are servers with too many failed health checks but are green most of the time.
On a network level, I don’t see any interruptions.
Services on those backend servers are browsable and are operating normally.
Does anyone have any suggestions?

Here is the screenshot from the stats page:


Since we were short on time a simple restart of the server solved the problem temporarily. There is something wrong with the services I guess so I’m pushing this back to our devs :smiley:
