I've been having problems with the Update manager, and I can't log in using my username/email and password. I suspect that in my case the problem is more to do with zscaler, which is an web filter. My suspicion is that it is blocking access to the itoo user account, and can therefore not verify them.
Any suggestions? I'm trying now to find out how to manually update all the libraries, without being able to log in to the updater... Ive got this problem with all the updated machines that I've updated so far, which means I'm down to 1 workstation and 2 render nodes which remain un-upgraded.
