Hello, I've got a problem about entering one spesific web site. 2 days ago everything was okay but yesterday I somehow couldn't enter Gmail with Opera GX. The page wasn't loading. First, there was an error about certificates and "ERR_SSL_PINNED_KEY_NOT_IN_CERT_CHAIN" was written down there as an error code I presume. Then I tried to run the page with VPN (not with the Opera's VPN) and it worked. But when I turn VPN off, error starts all again. The error has changed into "ERR_FAILED".

Afterwards I checked if I can enter with Opera's VPN, it worked for Asia and NA&SA locations, but not for the Europe.

I tried to reach the pages with other browsers (Opera, Chrome) and I didn't encounter with any problem, only Opera GX has this problem. I tried to clear cookies, reinstall Opara GX. Nothing helped. Did anyone else also encounter with this problem and manage the solve it?

@flaks use dark mode, then you'll see the error message

@burnout426 Unfortunately, it didn't work for me
