Thanks for checking that. Another set of sanity-checks: you've run the verification commands, to ensure the cert and your private key match?
>From the doc: openssl x509 -noout -modulus -in concat.crt | openssl md5 openssl rsa -noout -modulus -in myserver.key.pem | openssl md5 You should also be sure to verify the crt file itself openssl verify -verbose -CAfile concat.crt concat.crt Also, are you sure that the certificate matches the requirements of the platform <https://cloud.google.com/appengine/docs/python/console/using-custom-domains-and-ssl#app_engine_support_for_ssl_certificates> ?
