Most answers will tell you that you have a duplicate certificate. This is true for my case but the answers left out how to do it.

For me, my account expired and I have to get a new certificate and install it. Next, I looked at Keychain and removes the expired certificate but still got the error. What works for me is actually searching for "iPhone" in Keychain and removing all expired certificates. Apparently, some of it are not shown in System/Certificates or login/Certificates.

Hope this helps!
