You just might want to open a support ticket having all these upgrade issues as they will be able to help more by checking the logs.  If rebooting and checking the logs yourself does not help.  Also ensuring the correct credentials and no firewall blocks.

​@safiya, ​@Madi.Cristil, I believe this would be better suited to to the discussion boards as it’s a question, not a blog post. Could this be moved?

​@fjl, I agree with Chris, you should open a support ticket for this issue.
