Why does Yandex Payment give an SSL error, if any?

Question

Yandex

Customer site. We set automatic payment using the library for working with the API. Throws this error when getting a token.

Fatal error: Uncaught exception 'YM_ApiConnectionError' with message 'Could not verify Yandex.Money's SSL certificate. Please make sure that your network is not intercepting certificates. (Network error: SSL certificate problem: unable to get local issuer certificate)' in /var/www/u0555648/public_html/djonny.ru/lib/YandexMoney/ApiRequestor.php:96 Stack trace: #0 /var/www/u0555648/public_html/djonny.ru/lib/YandexMoney/ApiRequestor.php(51): YM_ApiRequestor->_handleCurlError(60, 'SSL certificate...') #1 /var/www/u0555648/public_html/djonny.ru/lib/YandexMoney/ApiRequestor.php(16): YM_ApiRequestor->_curlRequest('https://sp-mone...', 'grant_type=auth...') #2 /var/www/u0555648/public_html/djonny.ru/lib/YandexMoney.php(58): YM_ApiRequestor->request('https://sp-mone...', 'grant_type=auth...') #3 /var/www/u0555648/public_html/djonny.ru/access.php(36): YandexMoney->receiveOAuthToken('A55E1EC37F83CCF...', 'https://djonny....', 'F875F67BC5896B1...') #4 {main} thrown in www.site.com

The site has a certificate from Let's Encrypt. Yes free. Doesn't he fit?

Answer 1

This is not a problem with your certificate, but with the fact that the server does not seem to have a root for Yandex. You need to update the package ca-certificatesor similar.
