Issue abstract: ERR_SSL_PROTOCOL_ERROR
Detailed description: Since yesterday evening I get this error and similar ones on every website I try to visit using any browser except norton secure. This includes even your own norton website. I tried using chrome, firefox, edge and a few others and only norton secure still works. This all started when the UI changed to the current version. After uninstalling Norton all access is restored, so it’s definitely a norton issue, but I have no idea what got changed after your forced update. Online games aren’t affected (though I do feel I’m getting more ping spikes and dc’s), but even apps like X and facebook are not working anymore.
Product & version number: Norton 360 v.24.9.9452.995
OS details: Windows, just did a full winupdate to see if everything was up to date and check if something was interfering
What is the error message you are seeing?
If you have any supporting screenshots, please add them:
Had a similar issue on Sunday after update, Firefox worked OK, Edge OK for a while then would only open window then just sat there constantly showing ‘downloading’. Uninstalled Norton thru’ Windows uninstaller (NRnR coming up with error). After reboot Edge working OK. Went into on-line account, selected install on new computer, setup file downloaded, installed, Edge and other issues with NEW version solved (for now any way). I am base in UK, had various issues before with updates & remove & restore.
