There's one other: smtpmail-debug-verb.

Is smtpmail-send-it at all invoked in this scenario?  Or does the
failure happen before it is called?  If the latter, then smtpmail's
debug facilities will not help you, and I suggest to add 'message'
statements to network-stream-open-starttls to see what goes wrong
there, and why.  (I couldn't even find the place from which the error
message you cite comes.)
