I only added it to my MacBook Air and not my iMac but after adding it to my iMac, everything works fine. I recently installed Sophos Home on my computers and forgot I had to add the IP address for the Sophos XG web GUI to the Sophos Home exceptions list.

Both the iMac and MacBook Air have the same exact Sophos certificate, so I'm not sure what's going on.Įdit 2: Turns out it was Sophos Home (antivirus) that was causing the issue. I tried deleting and reimporting the Sophos certificate on my iMac but still the same issue. I am able to access the web GUI just fine with my MacBook Air. I can, however, access the web GUI using Chrome although I still get a warning page.Įdit: Apparently this is only on my iMac. I was able to access the page last night without any issues. I haven't updated my computer or Sophos XG, so I'm not sure why this suddenly started occurring.

When I click 'view the certificate', it's showing the same one it always has which is manually set to trusted by me (SophosApplianceCertificate). Even if I click the 'visit this website' link to bypass the warning, it simply goes back to the same 'This Connection is Not Private' error. I get the 'This Connection is Not Private' error. Suddenly today I can no longer access the Sophos XG web GUI from Safari.
