The oauth proxy is failing because the cert on community.skunkhenry.com is for

CN = *.community.skunkhenry.com

But the oauth proxy is trying to hit

Post https://community.skunkhenry.com/oauth/token

the *.community.skunkhenry.com cert does not cover the root domain so that's where the X509 error is coming from.

I don't have visibility into the APB projects but there are cluster level variables that can be set to only keep x number of failed or successful deploy pods on the cluster, I'll try find some documentation and report back, it won't delete failed projects but it could limit the number of pods which could be a step forward.
