Good morning all,
Due to some unsuccessful experimentation I had to rebuild my computer. Now I'm back to not being able to access vCenter but the previous fix won't apply itself. Here's the error when logging in to vCenter:

In Firefox there's usually an icon I can click to allow access but not here. So when I go to add a security exception Firefox tells me the certificate is just fine:

At first glance one would think the error would lie with Firefox. Some of you may have noticed that I blacked out the domain name in two locations in the first image and it's not being included in the second one. I added the domain name in the Add Security Exception section and it's working now. I hope this helps others who overlooked the same thing I did.
Thanks,
Joe B
