I think I have found a fix!!!!
I had noticed that a successful webpage access had the following format (for me in UK) www.facebook.com/en-gb whereas www.facebook.com just returned an error page as posted earlier.
The difference being I now got a facebook page which although not logged in it...
I should add that all was normal until only a day or two ago using Ublock, Bitwarden and Bitdefender etc in all three browsers (Brave, Chrome, Edge). I do wonder if a bad update or corruption has happened as the target?
No adblockers (first things I removed) . I use Bitdefender Total security but have switched that off totally with no change. Only other extension is Bitwarden for managing passwords.
z3r010 I used the Chrome Console and the following is the result
kl_klr6Mqr9.js:71 ErrorUtils caught an error:
GraphQL server responded with error 1675030: Error performing query.
[Caught in: caught error in module a [from CometSSRMultipassBoundary.react] (base)]
Subsequent non-fatal errors...
I did have some small success late last night (I am in UK) when following the 2FA suggestion by TESTER I reset up login using 2FA via mobile (which seems unaffected by the Windows issue). Suddenly the Brave browser on my laptop allowed login and device registration? Other browsers on the same...
DRU2, Unfortunately I did all that and since I last posted checked in via mobile to my account to reset 2FA in case that was the issue. Still neither my desktop nor my laptop see anything other than what I posted earlier
What you see is more or less what I would expect.
Gotta go for the moment ALL and thanks for the very smart suggestions. Please if you think of or spot the answer please post and I will try it. When fixed I will post back to tell you what my fix was.
BamaInArk correct, mobile is however logged into facebook account. I reckon if I logged out I would get same result. I did tether as I wondered if this was an ISP issue but that has eliminated that.
TESTER I followed the instructions (though I had already disabled synch in Chrome and always clear all history every day) but repeated all again but to no avail I am afraid.
Definitely odd this.
