So my problem is that when im loading websites with https content, the https domains take forever to timeout which slows down everything which is really annoying.
So I already configured ufw to reject port 443 traffic and allowed traffic for port 22 and 80.
I also tried flushing my dns cache.
eg. when I try to connect to https://googletagservices.com/ I get an timeout.
So I hope you guys can help me.
