“Failed to connect to Salesforce.com”

Well, I wouldn’t expect a debug email from SF, as they never got the submission.

That PHP notice is a red herring, it’s not the issue.

This is almost certainly… that your server’s version of Curl is out of date and/or lacks support for TLS 1.1+.

Thank you.

I think TLS 1.1 is supported:
cURL support enabled
cURL Information 7.19.7
Registered Stream Socket Transports tcp, udp, unix, udg, ssl, sslv3, tls, tlsv1.0, tlsv1.1, tlsv1.2

Ok, thanks for that info, that may not be the issue. however, note that PHP’s curl extension may be different than the curl version used on the command line.

The gist is: Salesforce failed to receive the submission — why can be hard to discern, as SF doesn’t really give any reason why: it just returns a failed HTTP status code.

Sometimes I can find the reason, but it requires debugging the connection to Salesforce on your server, which falls under premium support.

You’re welcome to do some poking around, but the reason is almost always server configuration related. The plugin is using a wp_remote_post which uses a common and highly compatible HTTP library under the hood…

I ended up changing the url here and it seems to work, now:

if( $form_type == ‘case’ ){
$url = ‘https://webto.salesforce.com/servlet/servlet.WebToCase?encoding=UTF-8’;
}else{
$url = ‘https://webto.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8′;
}

– https://www.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8′
+ https://webto.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8’

Well that would do it, but are you using an old version of the plugin? Those urls were updated ages ago.

The version number was the latest, but I see now that it had been modified by a previous developer. Not sure how they managed to report the latest version but not keep the latest urls on that line. Inheriting websites is like a box of chocolates…

Thanks for your help!
