"Suspicious connection blocked"?

At this moment I am barely typing through notifs interrupting me every 5 seconds.
It's been 2 hours like this, out of a sudden. I type from google chrome because not a single page in Opera (my
main browser) works. On each website I see "your connection to this site is not secure", the "DNS_PROBE_FINISHED_BAD_SECURE_CONFIG" error and bitdefender errors say "opera.exe tried to connect based on an untrusted certificate from security.cloudflare-dns.com. We blocked the connection to keep your data safe as untrusted certificates are issued by unrecognized certification bodies."
I have of course restarted my router, rebooted pc, restarted my IP, cleared dns cache... I have no idea what else to do to fix it. It's unbearable to work with.
