I had a few problems with vSphere Update manager and I want to share those with you. When I was running a test a few days ago, I noticed that the Update manager was not working. When I was looking for these in VMware’s KB’s, I have found a few other KB’s and I wanted to share these.
Because of a firewall you have in your system, you may not be able to upgrade. I had a problem like that and when I allowed the port on firewall it solved. About this problem, those KB’s below will be helpful to you.

And I’m sharing a small picture about vSphere’s diagram.
At the list below, you can see the port list that needs vSphere Update Manager.
