I saw this was a problem in older versions, but in 6.5.0 for Mac when I try to use Design Link to search for parts I get the following error:
Error while accessing 'https://api.element14.com/pffind/services/SearchService':
6 SSL handshake failed
If I put the URL in my web browser I get the message that "Our website is Under Maintenance" but this has been going on for a few days now.
