Cloudflare Support

A 522 error means we were unable to reach the origin web server at all. 

There are a few main causes of this: In all these cases, it’s worth checking that the origin web server is active and accepting HTTP requests before going further here, and also that the DNS settings in your account with us are set correctly.

What constitutes a high load based on the load value can differ depending on the computer and the software running on it, but generally speaking a load average of over 10-20 or so could mean that the server is overloaded.

There is a network routing issue between Cloudflare and the origin web server This is is more difficult to troubleshoot than the other causes, and it’s best to make sure that the other potential causes have been ruled-out before checking this.

If the origin server does not send a SYN+ACK back to Cloudflare within 15 seconds, a 522 error will occur and the connection is closed.

Another condition for the 522 timeout occurs when the origin responds with a SYN+ACK and established a TCP connection, but never responds to the request with an ACK within 90 seconds (A 524 condition ACKs the request, but waits too long to send the response).

If you are an email administrator or you have a third-party company who hosts your email and you are receiving one of the automated email responses listed below, your email server’s IP address (know as a MX Address) has been prohibited from emailing EarthLink customers: 'There was an SMTP communication problem with the recipient's email server.Please contact your system administrator.

Go toearthlink.net/blockfor details.>' This could happen for any of several reasons: Instructions To have the block removed and be able to send email to EarthLink customers, you will need to forward the bounced email to blockedbyearthlink@abuse.earthlink.net with the subject: Blocked <your email server's IP address>

If and when email blocks are implemented, if someone sends an email message and the sender's IP address or SMTP (outgoing mail) server is on one of these block lists, then the incoming email is blocked.

These requests must contain the bounce message received by the sender, so unblock requests are best submitted by the owner of the server, or the sender of the original email message.

Additional Information If your email server has been blocked by EarthLink, you may want to check other third party block lists to see if they have listed your IP as well.Being listed on these block lists could lead to your having problems emailing domains other than EarthLink.
