Hello

Our jenkins is accessible using url jenkins.domain.com/prod

Was trying today to access the monitoring page of a build agent, from agent page.
Found out JENKINS-70279 probably introduced a regression, breaking the Build agent monitoring page in our case:

Most of resources are wrongly served from root url jenkins.domain.com/monitoring, instead of jenkins.domain.com/prod/monitoring, resulting in 404 for all pages.

Note navigating to monitoring from the main /manage page is still working, but gives less information.
