CBSubs & Stripe issue

Hi,

I currently have 2 issues (that may or may not be related) with CBSubs:

1. If I access CB Plugin Mgmt I can see I'm running CBSubs 4.3.1 in the list of all plugins.
If I go to CBSub payment dashboard it shows at the top "unable to contact update server, error 0"
If I got the CBSub Settings -> Global , it shows installed version '---' and latest version available ' ? ? ' , both in red.

2. I have successfully used the stripe test server for test payments in the past. Currently test payments fail with a very generic error: " stripe Single payment unknown error: Submitted payment didn't return an error but didn't complete. "
Looking at the Developer dashboard in Stripe, I do see the API and Webhook calls being registered as successful and no errors in the Strip log.
I'm adding a screenshot of the end-user view with the errors shown.


Note:
I have configured webhooks.
API version selected in CBSubs is 2018-02-05 , also tested 2019-03-14 (latest option in CBSubs)
API version selected in Stripe is 2018-07-27. I have also tested this with 2019-08-14. Those are the only options I have to select in Stripe as API versions.
CB version 2.4.2+build.2019.08.26.19.00.58.18087aaa5
Joomla version 3.9.11

Let me know if you need more detail.

Your server is blocking communication with ours causing the version check to fail. Could be a firewall setting or could be a installed security extension. It's not critical to the functionality of the plugin though as it's just a version checker.

Navigate to CBSubs > History Log to review the errors. Be sure to also check CBSubs > Notifications for any failed notifications.

API version selected in CBSubs is 2018-02-05 , also tested 2019-03-14 (latest option in CBSubs)
API version selected in Stripe is 2018-07-27. I have also tested this with 2019-08-14. Those are the only options I have to select in Stripe as API versions.

It's safe to set the Stripe API within your Stripe account to 2019-08-14 (latest). Then within CBSubs Stripe set the version to 2019-03-14. We only add a new version when breaking changes that impact CBSubs Stripe are made to Stripes API so in most cases it's fine to use latest.

Are all Stripe payment methods having issues or just iDEAL?

I have set the API versions as indicated. Thanks for clarifying.

I just tested again with iDeal (its the payment type we want to use); after registration form, we get to the payment form. Clicking the payment button forwards us to the Stripe test page. I can select Pass or Fail the payment. I select Pass. I get send back to our website and the errors shown in the original screenshot are seen again.
Logs section of CBSubs shows:
- Info - User subscription record created with status: R
- Info - Store payment basket
- Error - stripe Stripe Sources API HTTPS POST request to payment gateway server failed.: Submitted source request didn't return an error but didn't complete. Please contact site administrator to check error log.
- Error - stripe Single payment unknown error: Submitted payment didn't return an error but didn't complete.

No other errors seen.

CBSubs Notifications only shows old entries using Stripe test with iDeal that completed successful. It shows no recent notifications.

Stripe Developer dashboard shows API & webhook request as successful.

Next I tested MasterCard. (we are not going to use it, but testing anyway): after registration form, we get to the payment form. Clicking the payment button, add the MasterCard details. Click submit. Errors in the log:
- Error - NOTICE: Undefined index: cvv in /var/www/vhosts/nvad.nl/httpdocs/components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/processors/stripe/cbpaidsubscriptions.stripe.php on line 581
- Error - stripe Single payment error returned 8888: Submitted payment didn't return an error but didn't complete. Please contact site administrator to check error log.

Let me know if you need more.

- Error - stripe Stripe Sources API HTTPS POST request to payment gateway server failed.: Submitted source request didn't return an error but didn't complete. Please contact site administrator to check error log.

Your server is unable to reach Stripe via HTTPS cURL call. The same issue you're having with the version checker. Something is configured wrong on your server as it's not able to communicate with external servers. Without that being fixed you won't be able to really use any payment gateway properly. Recommend contacting your host and having them take a look.

Looks like "Ask for CCV2/CVC2/CID" was disabled within CBSubs > Settings > Credit Cards, which is required by Stripe and many other gateways. Have added a bug ticket to account for this, but regardless it has to be enabled for Stripe.

Thanks. Done some more testing:
I can see that the Mastercard payment button isnt getting to Stripe as the Stripe Dev dashboard doesnt show a hit on the API.
I switched the 'Payment Button method' to 'Hosted'; got no hit on the API and got the error "stripe Stripe Checkout API HTTPS POST request to payment gateway server failed."

This seems to confirm something is blocking the connection.

As this is a hosted server; got any pointers on where to look? The apache log's seem show have no errors.

Could be a firewall configured by your host, could be mod_security blocking the request, could be PHP incorrectly configured and not allowing outbound HTTPS calls, could be a Joomla security extension (unlikely, but possible). Best approach is to contact your host regarding outbound HTTPS calls failing.
