I had to fix the fan of my laptop and therefore had to remove the battery. Ever since, I`ve been unable to use my browser, because for every second site I see the following error message (even for google.com).
*Your connection is not private
Attackers might be trying to steal your information from www.google.com (for example, passwords, messages, or credit cards).
www.google.com normally uses encryption to protect your information. When Opera tried to connect to www.google.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be www.google.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Opera stopped the connection before any data was exchanged.
You cannot visit www.google.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.*
- I use Opera 87.0.4390.36
- Win 7 x64
- My clock has been set correctly - also in the BIOS
- Uninstalled Opera - No luck
- Do not experience the same issue with the alternative browsers that are installed on the laptop
I am out of ideas. Do you have any? Thank you.
