This is my first post to the forum. We run multiple instances of WW, one instance per member College, and each instance lives on a dedicated VM. We're running WW 2.15 on RHEL8 and users access the server through a F5 load balancer, though with one server per site we aren't actually doing any load balancing with it. The F5 just takes care of public-facing SSL and IP.
The setup has been stable for some time, but we recently started seeing an error when using the file manager. I can click on File Manager without issue, but clicking on anything in the file list, whether directory or file, generates this error:
