As a wild guess, I will speculate that you are declaring a certificate hash as SSL_key_file on line 22. If so, and the server's certificate has changed, you will need to update that choice of pinned certificate — after confirming with your provider that the certificate actually has changed instead of you observing a MITM attack.

Also, as another monk mentioned, you seem to be using very old modules — your provider may have discontinued support for SSL and TLS prior to 1.2; if your copies of the relevant libraries are too old to support TLS 1.2, you would not be able to connect.
