Firefox is blocking connection to my internet service provider web site, how do I correct this?

Graushadow95

since last Saturday every time I attempt to go to the iserv.net web site I get a "unable to connect" screen. Windows Explorer and Google Chrome have no problem accessing the site from my CPU.

I have gone through everything in the Options/Preferences area and can't find anything that will correct the problem.

Did the site ask for certificate update or verification? That can also cause block internet if the certificate don't match. Check your certificate or update them to see what happens.

Didn't help. I checked for a certificate and it states that it is not a secure web site.
