I've had an ongoing problem since I started using my Galaxy Note 3, which affects the standard built-in Internet browser. Randomly, when trying to access a webpage, the browser will return the error "Unable to connect to proxy server". All other web-accessing things work fine - Twitter apps continue to update, I can still send and receive emails, online games, Amazon and Ebay apps still work, the Youtube app is fine, Whatsapp has no problem. The Google search function will still work, and will return me the usual list of websites in response to a query, but if I try to access any of those search results, I get the proxy error. The only way I can clear it is to go into the application manager in settings, find the Internet app, force close it and clear the cache, and then it'll all work fine again, for a while, until the next time it decides to die on me. I can't say for sure whether I only get this problem when I use Wifi, but certainly most of the time that's when it happens. It's a Note 3, running Android 4.3, using the standard Internet browser. Any ideas? Anybody else having the same issue?
