How to Solve Error 521 Cloudflare?
I keep getting a error 521 on a site I have running the one-click WordPress install on a Ubuntu droplet. I saw on Cloudflare’s website that you need to make sure their IPs are whitelisted which I did through the firewall in networking. The SSL I have activated currently is Full (non strict). I found another thread that suggested running this command: iptables -A INPUT -p tcp -m tcp –dport 443 -j ACCEPT
This did not solve the issue for me. What is odd is that I can refresh the page sometimes and it lets me go to the site, but when I navigate to another page it happens almost every time, but again allows me to go through if I refresh.
Any help would be greatly appreciated!
