For what it's worth, removing the Simple Theme plugin resolved our problem.

Thanks Ivan, But no, as I said there's no proxy of any sort involved. It's just a plain Jenkins installation on a VM that's directly connected to the target network. -- Stefan On 28.01.2022 10:33, Ivan Fernandez Calvo wrote:It looks like a reverse proxy wrong redirection rules to me (I hit it in the past), you can check with `curl` the redirections and who make them, something like curl -Lv -u user:${PASSWORD} ${JENKINS_URL}/iconSize?16x16 El jueves, 27 de enero de 2022 a las 16:17:49 UTC+1, Stefan Möbius escribió: Hi, One of our Jenkins deployments recently started acting up. When you access it, you get prompted for your credentials (no surprise there), it apparently accepts them, but then fails to load any further page. Looking at a network trace shows, that requests to /iconSize?16x16 and /j_spring_security_check are answered with a redirect to / Anybody able to suggest what’s wrong? Yes, I am aware of the various questions to similar issues, but I’m not using OpenID, nor a proxy. Jenkins security is configured to Active Directory, which appears to work. The setting “Require TLS” doesn’t make a difference. This is Jenkins 2.319.2. All installed plugins are up-to-date. I’ve tried to play around with extended logging, but since I don’t know what I’m looking for, I’ve had little luck. What could I look for?
