Glad you figured that out.
I've used three SSL evaluation websites to help me with intermediate certificate issues:
https://www.ssllabs.com/ssltest/analyze.html (will show the names and details of the certs, missing or not
https://www.wormly.com/test_ssl (quick SSL tester, will point out if intermediate certificate is missing)
https://www.digicert.com/help/ (will show a green chain link between certs when they're all there *and* in order)

Subject: FIXED - Re: Broken SSL cert caused by router?
I'd like to thank everyone for their kind responses. One person who
responded off list and bothered to look at the returned certificates
pointed out, and correctly it seems, that my original setup was missing
an intermediate certificate. The site was returning 'valid ssl' and all
browsers got the green lock and offsite ssl tests came back ok, but
apparently the missing intermediate means it would have had to have been
fetched and that was the part that was failing at the customer site.
Once I put the intermediate certificate in there, the customer site was
able to access https without fail. I have not had an opportunity yet to
examine in detail the config of the meraki router there but it's either
a routing problem or a DPI problem. If I get an answer I'll post again
with my results.
