Error during initial configuration
I'm getting an error when trying to proceed past the 'Getting started assistance' page of Setup:
The SSL connection could not be established, see inner exception.
This occurs whether I leave the fields empty or not. (UX conflict: the 'GET FREE ASSISTANCE' button implies that the fields are required, even though instructional text nearby states that they're optional.)
It also occurs when specifying a mail server that doesn't use SSL.
I see now (by looking at the decompiled source of v2.3.3) that the next Wizard Step is Usage statistics. That tidbit eluded me at first, as the button for that remains dimmed until hover. That was a bit of confusing UX, which you've likely addressed in the new RC version.
The other issue is still pertinent, however; I was unable to use the Support Wizard Step due to the SSL connection error.
