"Server certificate untrusted" error in iPhone application

Question

I am using my iPhone application on my iPhone 3G OS 3.0.1 without any problems. The application connects to an API URL at https://api.serverdensity.com/1.0/ and all requests go through it.

A user of the app has reported that they are now suddenly getting an error "untrusted server certificate". No other users are experiencing this issue (that I'm aware of) and I cannot reproduce it.

The SSL certificate is a wildcard certificate on *.serverdensity.com. It is purchased from GoDaddy and is valid until May 2010.

Further, the user is running OS 3.0.1, the time/date are set correctly on the device and if he visits the API URL in Safari, it loads up correctly.

Any suggestions for the cause of this?

Answer 1

I had the same problem!

Did you install there "Intermediate Certificate Bundle"? If you don't then you will get the untrusted server certificate on all mobile platforms (and some PC ones as well).

Web Site Quote:

Before you install your issued SSL certificate you must download and install our intermediate certificate bundle on your Web server. You may also download the bundle from the repository.

Check out the GoDaddy SSL install instructions for your web server setup.

The Intermediate Certificate Bundle can be found here.
