I got this tonight--first on the laptop, then on the phone. I was able to get my phone browser to work again by going to incognito mode under the browser menu/incognito mode. After searching for others with this new issue, I made an account through the phone, then had to go to my email (via email app), then back into the browser. This time, started out of incognito mode, but it put me right through to get here to post this. Haven't tried using tether again.
