    Just a thought, you say you are using Bitdefender firewall and by rights, when you installed it, it should have disabled Windows Firewall. Just to be sure though, you may want to go to "services" and verify that it is indeed disabled.
    Windows Firewall was running in the background. I just disabled it, not sure if it affects it though.

    Which browser are you using?

    I had the same problem too using Firefox x64, with the Bitdefender Total Security 2016

    What i did to test if was a bitdefender problem was:
    This warning is presented by a web browser when accessing a site that has a security certificate installed (for SSL/TLS data encryption) which cannot be verified or installed by the web browser.
    To solve this issue, we recommend you to temporarily turn off “Scan SSL” feature in Bitdefender as follows:

    • bring up the main Bitdefender interface
    • click on Modules
    • From Settings Overview choose Protection
    • In the Protection tab choose Web Protection use the switch to temporarily turn off Scan SSL feature

    Now close the Bitdefender window and try to access the webpage one more time.

    Turn on again SCAN SSL feature on Bitdefender.

    In my case i had to import certificate to firefox from mitm_cache bitdefender folder.

    I use Chrome and Bitdefender Total Security 2016 v20.0.24.1290. I attempted your method and used Firefox to import the certificates but couldn't access anything on Firefox. I used chrome again and I can access before but not in incognito mode. Also, for some reason Google's certificates are not replaced with bitdefenders certificate when I was looking through them before.

    I have turned off Bitdefender's Scan SSL setting located under Modules>Protection>Web Protection. And when the issue occurred again, I got a DNS probe error and then proceeded to change my DNS settings in my network adapter configuration under IPv4 properties to Googles DNS (8.8.8.8 and 8.8.4.4) and my problems went away.
