Since quite some time our team experiences problems with the warnings-ng plugin, where in different browsers, OS'es and times sometimes the errors are not displayed at all, some ajax request just ends in a timeout.
I already filed a bugreport for the warnings-plugin, but the maintainer said that he doesn't even know where to begin with, since the ajax request ect. are abstracted by jenkins.

Recently i again experienced the problem and had the console in my browser on, where i noticed some errors, right before the warnings again didn't show up.

After experiencing this error, a request to

<jenkins-url>/$stapler/bound/<random-string>/getTableModel
runs into a timeout.

There are no entries in the jenkins log.

If there is any additional information i can provide here i'm happy to!

Thanks you, Stephan
