I’ve been trying to validate the card markup for the domain nextpeak.co. When I’m not using a https url, the validator works fine, but after submitting a https url to the validator, I’m getting a “ERROR: Fetching the page failed because SSL handshake error.”
I have been in contact with my hoster (http://uberspace.de) and they think it’s because the uberspace servers are using too secure SSL and the java on twitter’s servers isn’t able to handle that.
Test URL for the validator: https://nextpeak.co/checkin/NZjlDajz
The domain nextpeak.co gets a Grade A when testing the SSL implementation with SSL Labs, so I don’t think there’s anything wrong with the SSL setup itself: https://www.ssllabs.com/ssltest/analyze.html?d=nextpeak.co&s=126.96.36.199&latest
Is anybody from Twitter able to help me with the validation?
