Alex, et al, Thanks very much for the suggestions. The tip-off that HSTS issues may actually be a symptom, not the problem, was key. Turns out I did not properly install my self-signed root certificate into my laptop. Once I fixed that, everything started working. Thanks again for the help! -Dave On Wed, Jul 9, 2014 at 1:59 PM, Alex Rousskov <rousskov@xxxxxxxxxxxxxxxxxxxxxxx> wrote: > On 07/08/2014 08:17 PM, David Marcos wrote: > >> b.
