Oh I see. Just wondering if it was the update manager service that had crashed as per the article I referenced.

I was able to login to VCSA no problems it was the update manager tab that was failing to load and in the tasks window it was trying  to connect to the vmware servers to download patch definitions and failing. Reversing the edit in the article referenced fixed it for me on VCSA 6.5UQ3

Not sure what to suggest as I don't have the lifecycle manager I think that's 6.7 and above isn't it?
