<div dir="ltr"><div dir="ltr">Hi Ingela,<div><br></div><div>Curtis' example server from his first message, <a href="http://hooks.glip.com">hooks.glip.com</a>, presents its certificates out-of-order. The correct order is Peer -> Intermediate CA 1 - > Intermediate CA 2 -> Root CA but they get presented as Peer -> Root CA -> Intermediate CA 2 -> Intermediate CA 1 and this returns the "Unknown CA" error. You can confirm this by running `openssl s_client -connect hooks.glip.com:443`.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Nov 7, 2019 at 1:23 PM Curtis J Schofield <curtis@ram9.cc> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> <div>Hi Ingela</div><div><br></div><div>Thank you for your attention- perhaps Micheal can explain this better.. <u></u><u></u></div><div><br></div><div id="gmail-m_-5220970652841391182protonmail_mobile_signature_block"><div>Sent from ProtonMail Mobile</div></div> <div><br></div><div><br></div>On Thu, Nov 7, 2019 at 6:55 AM, Ingela Andin <<a href="mailto:ingela.andin@gmail.com" target="_blank">ingela.andin@gmail.com</a>> wrote:<blockquote type="cite"> <div dir="ltr"><div>Hi!</div><div><br></div><div>I
