As the title states, adguard is blocking all webpages from loading on the newest windows 10 insider fast-ring build. Windows 10 Pro Insider Preview (64-bit) Build 14942.rs_prerelease.161003-1923 My guess is that it's something to do with the way AdGuard's certificate is handled under this new build, but don't quote me. The reason I think this is because web pages will not load with adguard enabled. The second I disable adguard, however, all pages load just fine. Hope a fix or an update is released fairly quickly, and I hope I'm not the only person experiencing this. I don't post much, mostly because adguard is mostly trouble free, but I had to bring this to the attention of the developers. Update: Disabling protection does not fix the issue, either. I have to completely close the program in order for any webpage to load correctly. Using Chrome, the latest build, I receive a ERR_SSL_PROTOCOL_ERROR, under any other browser, sites just will not load. Edge, Internet Explorer....it doesn't matter which browser I try, it simply will not allow the page to load. Exiting AdGuard, however, I can refresh the page, and it loads instantly. I just wanted to bring this attention to the forums so the problem (hopefully) gets resolved fairly quickly, plus, my license for AdGuard expires on October 25, 2016, so I wanted to file this as a bug and let this be known, to avoid this occurrence happening to anyone else.
