Hello,
The server may only support certain SSL versions, like SSL2; SSL3; TLS1.0; TSL1.1 or TLS1.2.
By using web_set_sockets_option("SSL_VERSION","TLS"), you'll force LR to use TLS1.0 when do SSL handshake, which may be not supported by server. and will cause following errors.
You can try set other SSL versions to see whether the issue can be solved. The SSL version preference is: '2', '3', '2&3', 'TLS', 'TLS1.1', or 'TLS1.2'
Regards,
Bingle
