500 error with "drupal_http_request()/stream_socket_client()" on the Pantheon

A technical issue on the Pantheon

The "cloudinary" module uses the drupal_http_request()/stream_socket_client() function to connect to a “https/ssl” sockets. Time to time PHP reports an error about “call undefined function“ for the stream_socket_client(). This run-time error provides a side effect for the "cloudinary" functionality and shows a 500 page for an end-user.

I assume a root of the issue could be in some custom patches/improvements for PHP on the Patheon (because I never get this error on the Lando recipe from the Patheon).

My suggestion is to use the "try-catch" statements in the "cloudinary" module.
