CloudFlare cannot connect to webserver on port 80

[user863]

I have a webserver running on port 80, and when I go to the origin IP, I can see my site fine.

When I try use Cloudflare, I just get the error 521 Webserver is down.

Hi there,
Is Cloudflare allowed through your server’s firewall?

Community Tip - Fixing Error 521: Web server is down

Error Try the suggestions in this Community Tip to help you fix Error 521: Web server is down. Background A 521 error happens when we are unable to make a TCP connection to your origin server. Specifically, Cloudflare tried to connect to your origin server on port 80 or 443, but received a connection refused error. This is often caused by security or firewall software and happens if the origin server has directly refused Cloudflare’s proxy request. [Banner in tip catalog] Quick Fix Ideas …

Having mod_Cloudflare instaleld could also help here if I’m not mistaken.

I am afraid mod_Cloudflare wouldnt help in these cases.

Oh no I’m mistaken. Sorry about that. I’ll fix my post.

[user863]

Yeah, It is.

Your site appears to be loading for me (Cloudflare is redirecting to https)

I’ll let @sandro take this over since I don’t seem to know this area too well. Did you try the link they shared?
