Twitter Card Validation Error


#1

I’m helping a client set up their first Twitter Card. We confirmed that our secure POST URL and parameters work correctly outside of Twitter. However, when I test the card within the Twitter Card tool, I get the following error:

Result: Failure. Error submitting card data: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed.

How can I resolve this error? Is there some change I need to make to our security certificate?

Thanks!

Hello, did anyone managed to solve this? My certificate is fine w/ Chrome (green lock)

  • Server certificate:
  • subject: OU=Domain Control Validated; OU=PositiveSSL; CN=api.properati.com
  • start date: 2014-09-11 00:00:00 GMT
  • expire date: 2015-09-11 23:59:59 GMT
  • subjectAltName: api.properati.com matched
  • issuer: C=GB; ST=Greater Manchester; L=Salford; O=COMODO CA Limited; CN=COMODO RSA Domain Validation Secure Server CA
  • SSL certificate verify ok.

But I stil lget the infamous: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed.

Thanks
