Is this issue resolved? if yes, please provide the solution. even am facing the same issue. It is taking lots of time to fix and am not understanding the root cause for this. This has been a blocker in the production environment,
We have been running our jenkins under tomcat for last 10 years until we upgrade our jenkins from 2.235.5 (LTS) to 2.263.1-LTS we had no issue.
Sure we will consider to move out of tomcat.
Nginx reverse proxy side seems no issues, because i have tested without nginx reverse proxy even in that too facing same problem.
it looks CSRF is causing issue with tomcat. still digging. hopefully will sorted out.
