USPS Timing out and not returning rates

[Wulf359]

I'm trying to sort out the USPS shipping module on a site and have followed all the destructions, have the API information put in, even went so far as to have USPS check to see if the IP address was blocked and any such blocks removed if any.... but still I get this:


United States Postal Service

Have been on the phone with USPS several times to ensure the site is using the production server and everything, but we're still getting the timeout error and they insist the problem is on my end.

"Connect timed out" is typically a server firewall issue.
Specifically, curl (the tool used to make a web request to the external server) was able to lookup the address of the USPS server and initiate the request, but the USPS server didn't respond. This means either your request didn't get out past your server's firewall, or the response didn't get back to you through your server's firewall.

The only team who can fix this is your server administration team, ie: your hosting company.

Contact their support team.

Over the past couple days, we've seen the same response after a 15 secondish page parse time. But, waiting a few seconds and refreshing once or twice usually received a normal response.

Based upon the lines at the post office, I just assumed the USPS servers were overloaded with requests and didn't bother with looking at logfiles.

Thank you, working on that now !!!
