I may have figured out what my issue is. Rereading the documentation my slowly and carefully, I noticed this tidbit:
If the host certificate requires an intermediate or chained certificate (as many Certificate Authorities (CAs) issue), you will need to append the intermediate or chained certificates to the end of the public certificate file. That sounds like it's probably my issue. I'll try to figure out how to do what it says now! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
