I have Verizon Homefusion internet access. I use AOL for e-mail. Earlier this year I could no longer access the AOL login site (mail.aol.com and login.aol.com). I have two Windows 10 computers each with two separate browsers. It fails on all. I can access AOL.com, but the same problem occurs when I hit the login button. It goes in an endless loop and times out. One computer is a tablet. I can login with it on my neighbors internet service. I bring it home and can access my AOL mail on Verizon. When I'm logged out on the tablet I can't log back in on Verizon. I was able to ping the site through the router. I downloaded the AOL app. I enter my name to go to the password site. It times out also.
New info. On the Verizon Iphone I was able to get to mail.aol.com. I set the Iphone to wifi to access the internet through the Verizon router. I wasn't able to get to the site with the router.
