Jenkins 2.234, AWS ec2 instance running jenkins container.
Jenkins URL: https://jenkins-backend.dev.cicdenv.com/
Resoure Root URL: https://builds-backend.dev.cicdenv.com/
Both DNS names go to an AWS ALB with host routing rules.
The server/resource root URLs are set in groovy hooky scripts:
JenkinsLocationConfiguration.get().url = ...
ResourceDomainConfiguration.get().url = ...
I haven't used a separate resource root url before.
I put a custom logo override into userContent and it is working which leads me to believe the resource root url setting is working, however the check against /instance-identity/ is failing in the configure page.
I don't think this problem is new in version 2.234.
