I’ve restarted my instance and now I cannot access the admin.website.com, receiving the 521 error.
I am kinda new on this and trying to read other similar topics but unfortunately don’t know how to act and I would require some help if possible.
I know that I have to:
Check your origin web server - how can I do that?
If you have just moved to Cloudflare and you are seeing a 521 over HTTPS, it is possible that your origin server has not been configured to allow port 443 be accessed by Cloudflare IPs* - Nope, it was working before reboot perfect
Make sure that you’re not blocking Cloudflare IPs in .htaccess, iptables , or your firewall - Where can I check that?
Thank you and stay safe!
