@Edent I don’t recall that error, no sorry. This part is a such a pain. If you have your code up somewhere I’d be happy to take a look just as a second pair of eyes.
@robb very kind of you!

@robb ah, I stuffed up the headers. Got them working now.
New error is "Verification failed for ..." Which at least is progress!
@Edent Excellent! (Was putting the kid to bed and only just started looking, glad you got it sorted)
