Sorry for the late reply. Line went down completely again. Honestly I have no idea what changed. It was working I went to bed, I woke it and it just would not connect.Same "automatically detect proxy settings" issue here, was called out to a local butchery this morning, emails kept coming in and I could ping sites, but nothing opens in a browser (apart from local connected devices - router, printer, cctv works fine). Static IP, default gateway and DNS all correct.
Browsers (Chrome, Edge, IE) would give 404 or invalid proxy settings error.
Removed auto detect proxy settings and everything works fine.
I'm curious, why today what changed? Default windows setting is auto detect, machine ran fine with auto for the last 6 months.
