Hi Suresh,

I guess the first article is about internet connection problem. I think according to the messages internet connection and dns resolution is verified.

And the second article is about collecting upgrade logs then suggests to create a case with GTAC. Unfortunately we do not have support for GTAC.

Any help will be appreciated. Thanks all.

Hi all,

The problem is solved by deploying clean install of the ova or ISO for version , then restore the database to it from version as mentioned at the first link Suresh sent above.
