NSLocalized Recovery Suggestion=Would you like to connect to the server anyway?
I spent considerable time trying to resolve this issue, scouring Stack Overflow and the rest of the web.
I had to manually trust it from the Certificate Trust Settings panel (also mentioned in this question).
I debated canceling the question, but I thought it might be helpful to have some of the relevant code and log details someone might be looking for. I even went back and reconfirmed that it automatically works up through i OS 10.
