Getting err_connection_timed_out for almost every website I visit

Hello, I am consistently getting err_connection_timed_out message on almost every website I visit with every single of my devices (laptop, phone, console, tablet). It's become completely useless when none of the websites load. I already restarted and resetted the router multiple times, disabled the firewalls and antiviruses, updated the network drivers but none of that seems to work.
