Hi all, just trying to get Jenkins set up for the first time and for some reason I’m getting this error when trying to view the help files of certain systems. Any idea what could be causing it? Thank you for the help!
So, while writing this post I had to log out and log back into Jenkins to get the details below, and it seems as though the issue resolved itself. Since I didn’t see any other posts about this, I figured I might as well still post it for anyone else that runs into the same issue.
