Bad gateway (502) on order confirmation [solved]

[Gorka]

Hi,

I'm setting up the Stripe module and everything works fine except for the final step (the order confirmation page displayed to the customer).

This is the URL causing problems: /gb/module/stripe/validation?type=checkout

• The order is generated properly and the payment status is correct.
• Payment is received in Stripe.
• Email is sent to the customer.

I'm using:

• Nginx/1.10.3
• PHP 7.4.

Notes/ideas:

• The backoffice tells me about a problem with TLS 1.2 (Install TLS v1.2 support on your server.). Could this be related to it?
• Could the 'gb' at the beginning of the URL what is causing problems? (/gb/module/stripe/validation?type=checkout)

It looks like it could be TLS 1.2 related: https://support.stripe.com/questions/upgrade-your-stripe-integration-from-tls-1-1-to-tls-1-2

Thanks for the reply @30knees.

It is weird since the server has TSL 1.2 support (I've checked it). And so does say the Stripe module configuration:

But, if I go to Advanced Parameters -> Configuration Information it says there is no support for TLS 1.2:

Any ideas?

I'm probably irrelevant here, but
/overrides/classes/mail.php is worth disabling if you have it, and this thread has an idea about http to https redirection and error-message checking.

Hi @veganline. Tried that but it didn't work.

What worked for me was changing the Ciphering configuration under Advanced Parameters / Performance to the following value (I had PHP Encryption library).

Has anyone else seen this problem?
