Unable to link to Drafts Action Directory

Anybody know why I get a “Sorry, unable to link to that host” message (it’s worded along those lines) when I try add a link to an action in the action directory?

I’m trying to post from my iPhone, if that matters. @greg-pierce, any idea?

Here’s a screenshot of the error message.

Okay, disregard. Turns out the issue was because I had a new account and it was limited to what it could do.
