Getting Http/1.1 Service Unavailable on iCloud login
Suddenly today, August 20 2015 I am getting "Http/1.1 Service Unavailable" when I try to log into my iCloud acct via Chrome or Mozilla Firefox. I have tried numerous times and keep getting the same result. Strangely, I CAN login via Internet Explorer. Chrome is my preferred browser. Can anyone tell me what the issue with Chrome and Firefox might be?? THANKS!
PC with Win 7 64 bit. Google Chrome up to date. Firefox up to date. Assuming a recent Win update as my computer restarted last night while asleep.
PC-OTHER, Windows 7
