HTTP Post not going through / Timeout related error message

Andrew Pfund — 

Example of the type of error message you’ll see:

In this situation it is most likely that your hosting provider is blocking any posts from Infusionsoft because their IP address appears on certain web spam bot lists.

In this situation you’ll need to contact your hosting companies support team and have them add

or

to your servers white list (the type of ip address that you add depends on your whitelist format).

After this the HTTP POST requests should be reaching your server without any problems. Please check the result and confirm that the website functionality is working as expected (for example check to see if a newly created user is able to log in with their auto generated password, etc).
