This is more an FYI and a question to find out WHY it's doing this, but I think I figured the answer out.
I have a MacBook Air running Yosemite 10.10.5 and I use both Chrome and Safari on it. We had Verizon Fios and switched when they sold to Frontier and now have BrightHouse as our ISP/cable provider.
Suddenly, I stopped being able to access some sites unless it was https.
For example,
http://www.google.com would not work, but
https://www.google.com would. Had no problem at other locations or before the change. Or if I tried to click on outside links to stories on Facebook, it would give me errors unless I manually went in and changed the http to https.
HOWEVER (before you say it's the network)...
I house-sat for friends (BrightHouse) a couple of years ago and had same problem. And they ran Win laptops with IE with no problems. But also, I haven't had that problem at other BrightHouse locations. (Hold on, don't say it's ISP or firewall yet...)
My husband has an HP laptop running Win10 and using FireFox--no problems. Our iPads using Safari--NO problems. Ditto phones and other devices.
ONLY my MacBook Air.
I started digging into both my Mac's network settings and into my new router's settings. Nothing I tried fixed it. THEN...I remembered that before, I had temporarily disabled Avast and boom, it started working.
So...I tried that. Sites are WORKING.
Um, okay. Well, yes, I'm on a Mac, but I will NOT go without protection.
I started digging into Avast and unticked the box next to the IPv6 setting in the web shield settings.
Problem solved.
My question is...WHY is it working?? And question to the powers that be, what can you do to FIX that problem?
