SSL Error using custom domain with Google App Engine

I followed the steps detailed here to use a custom domain with google app engine.

I'm the admin of the Google Apps account
I'm the owner of the Google App Engine account
I've added the domain to my Google Apps account through my App Engine account
I see my App Engine app in my Google Apps account
I set the CNAME "test" to point to ghs.googlehosted.com
I added the web address under my Google Apps account and it says "Your users can access my-app-id at: test.mydomain.com

Now when I go to http://test.mydomain.com, it redirects to https://test.mydomain.com and I get an SSL connection error (Unable to make a secure connection to the server.)

I called Google Apps customer support because I have a paid business account, but the customer service guy said that this falls under App Engine support and he was not trained in this issue.

Help!

Solution

If you've done everything correctly, you should be able to access your site at http://test.mydomain.com. It sounds from the error you're getting that you're attempting to access it at https://test.mydomain.com (https as opposed to http).

If you want to access your app over SSL at your custom domain, you have more setup to do, as documented here: SSL for a Custom Domain. The steps necessary are many and subject to change; that link is the official source of current information on the matter.

Update: From your updated information, it sounds like you may have secure: always set in your app.yaml, or the Java-configuration equivalent of this setting. It would be helpful if you posted your configuration file.
