How do I get support for the Workfront data connector

I have a connection to workfront that has stopped working. The history suggests reaching out to Workfront, but workfront said to contact domo. I guess the connectors are supplied by third parties? I haven't been able to google up the identity of the third-party provider. Also, was unsuccessful in creating a Domo support ticket. Error message on the page and no 'new' button to select.
