That may be the case, it's only been 8 days since the sync stopped working...

@leocg
Yes, even after I reinstall the problem continues.

*And in other browsers too i can login too...

@leocg
Yes, I deleted this entire folder, I uninstalled the opera and reinstalled.

And in other browsers too...

@leocg
Yes, I can login at https://sync.opera.com/web

@leocg
When entering the user name and password, the login field remains forever with a standby screen with a wheel rotating in the middle.
Just for test, I put the wrong password, but then a wrong login message appears.
I deleted the profile folder, uninstalled the opera and did a completely clean installation and the error remains the same.

I can no longer synchronize my opera since 2018/10/07
