AWS EC2 + Cloudflare

[Ida]

Hello!

I have created an EC2 instance on AWS and pointed my domain with Cloudflare to it. But now I keep getting this error:

Error 522

Connection timed out

Browser: working
Cloudflare: working
Host: Error

I am very new to this, but I understand that the error comes from the EC2 instance. However, can anyone explain to me why is this happening and how could I fix it please?

Thank you very much!

Error Try the suggestions in this Community Tip to help you fix Error 522 “ERR CONNECTION TIMED OUT” in Google Chrome or “The connection has timed out” in Firefox.

When this happens, you’ll see “ERR_CONNECTION_TIMED_OUT”. Quick Fix Ideas Make sure that you’re not blocking Cloudflare IPs in .htaccess, ip…

This explains why Errors like 522 are happening. Also this is not fixable from Cloudflare-Side but you have to configurate your EC2 to accept TCP connections from Cloudflare
