Proxy Server issues - Samsung Galaxy S5

A

AC Question

Hi all

I have a Samsung Galaxy S5. Got it a week after it came out and cracked the screen 2 months later (no insurance), but that's another story.

Since about end of June, I have had problems using the internet on wifi. It is not all the time, but quite a bit. I often get the message "Unable to connect to the proxy server" when trying to get to websites.

A similar issue is when clicking through to websites from social media sites and the page opens, but it comes to a "page not found" page on the overall site.

Both of these can be corrected by changed the Proxy from "Manual" to "None" on the particular wifi network configuration. However, this does not last and needs to be changed again and again for those sites to work.

Causing me to get through my data quickly! Please help!

Thanks

Charlie
