Webhook error: SSL: certificate subject name does not match target host name

Version 2

    Issue Description
    The error type "The remote server's SSL certificate or SSH fingerprint was rejected" occurs when the SSL certificate is being used on the main domain and not Sub-domains.


    Issue Resolution

    1. Check the URL in Admin > Webhooks
    2. Click on the webhook in the right corner.
    3. For example, if the URL is, https://onlineservices.test.marketo.com, the certificate needs to be valid on *.test.marketo.com and not just *.Marketo.com.
    4. Check this by verifying the certificate on "https://www.sslshopper.com" and all the certificates will be listed as Subject Alternative Name's if the certificate is valid on the sub-domains.

    For example:

    For Google.com "https://www.sslshopper.com/ssl-checker.html#hostname=google.com", the certificate is valid on *.Google.com as well as all the subdomains as listed in SAN's.
