Browser errors accessing VMware web clients

Browser errors accessing VMware web clients


I've been hitting a strange error when using my Lab at home that I'd thought I'd share here. IPMI and the VCSA appliance interfaces both work but the ESXi UI and vCenter web interface all fail on multiple browsers:

Here is the result "Secure Connection Failed" from Firefox:

Here is the result "This page isn't working" from Chrome:


This was confusing the heck out of me. I checked my Hosts file was pointing at the right locations, that the URLs were good - different browsers didn't matter. I thought perhaps some older encryption method wasn't supported in my browsers anymore but then tried disabling my antivirus. I'm using Bitdefender and after disabling it the URLs started working. Until today I couldn't figure out how to add exceptions/exclusions so there is how I did that:

I added in the vCenter URL and IP of the ESXi host and straight away was fine again. 
We've recently seen an issue where a Flash issue stopped IE working but this was slightly different. This might help someone else out there stumbling on the same thing!
