since the 8th June 2020 neither edge or IE were able to browse the internet, i then installed Chrome and that had the same issue. Internet connectivity was fine i was able to RDP to computers via secure gateway outside of my network, it was so bad i couldn't manage my router on local network from any browser either. after trying nearly everything i tried safe mode with networking and problem disappeared, so i decided to uninstall sophos, which also failed and i had to resort to sophosZap.. anyway that fixed the problem, but not one to leave it i reinstalled Sophos Home and the problem returned immediately. so i had to once again remove it Sophos. I am keen to get to the boytom of this as i prefer sophos to windows protection.
Hi pete day
Would you please confirm if you are using Sophos Home or is it managed by Central or Enterprise console? I would request you to join this Endpoint community group, so that I can move the thread to that community group.
