Did you mean: not posting back to response URL -Timed Out

Can somebody give me an idea what could be the problem?


We are using Opencart3.0 and SIM. Everything was working fine including response URL back to our site till March 24, 2018. Suddenly all the transactions went into "Missing Orders" starting March 25, 2018.


We get the following error:

An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card.

This transaction has been approved.

It is advisable for you to contact the merchant to verify that you will receive the product or service.


We were able to make successful transactions through following method:

1. Setting "x_relay_response" to "false" in opencart redirected to default receipt URL of and by clicking on a button it redirects successfully to the merchant site.

2. Forcing the site to run under "http" and setting the "x_relay_repose" to "true" and configuring "http" callback url in works fine. The response reaches the merchant site.



We were not able to get the response from and it times out when we use "x_relay_response" to "true" and when running under "https" and configuring "https" callback url in "response url".


Please help!




You need to implement TLS 1.2 and disable older types of SSL. That will fix your problem


Thanks. I will try and get back.

Have you got this working by updating TLS? Because it was working fine at our end till March 24,2018.
