This certificate has an invalid issuer Apple Push Services

📱 Fixing the "Invalid Issuer" Error for Apple Push Services Certificates

So, you're excited about implementing push notifications for your app. You go ahead and create a certificate to enable Push Services, but when you try to add the certificate to your Keychain, boom! An error message pops up, saying, "This certificate has an invalid issuer." What a bummer! 😫

But worry not, my tech-savvy friend! In this blog post, we will delve into this common issue and guide you through easy solutions to get rid of that pesky error. Let's dive in! 💪

Understanding the Problem

First things first, let's understand what this error message means. "Invalid issuer" simply implies that the signer of the certificate is not recognized or trusted by the system. In this case, it likely means that the Apple Push Services certificate you're trying to add is not issued by a trusted authority. Consequently, your app won't be able to establish a secure connection with Apple's push notification service. 😱

Solution 1: Check Certificate Validity

Before we proceed with any other solutions, let's ensure that the certificate you have generated is valid. Double-check the following:

1. Confirm that you have created the correct certificate type for push notifications. In this case, you should be using an Apple Push Notification service SSL (Sandbox & Production) certificate.

2. Verify that the certificate is not expired. Certificates have an expiration date, and Apple may reject certificates that have expired.

3. Ensure that the certificate signing request (CSR) you used to generate the certificate matches the one on your Apple Developer account.

4. Check if your Apple Developer account is active and in good standing. Sometimes, account-related issues can cause problems with certificates.

Solution 2: Revoke and Generate a New Certificate

If your certificate passes the validity tests outlined above, but you still encounter the "Invalid issuer" error, it's time to revoke the existing certificate and generate a new one. Here's how you can do it:

1. Navigate to the Certificates, Identifiers & Profiles section of your Apple Developer account.

2. Find the problematic certificate and revoke it.

3. Generate a new certificate using the appropriate certificate signing request (CSR).

4. Download the new certificate and install it in your Keychain.

By starting fresh and generating a new certificate, you might be able to resolve the "Invalid issuer" issue.

Solution 3: Trust the Apple Root Certificate

In some cases, your system might not trust the Apple Root Certificate, causing the "Invalid issuer" error. Here's what you can do to resolve this:

1. Open Keychain Access on your Mac.

2. Go to the Certificates category.

3. Search for "Apple Root Certificate."

4. If the certificate is not trusted (marked with a red "X" or labeled as "This certificate is not trusted"), double-click on it.

5. In the certificate window, expand the "Trust" section.

6. Ensure that "When using this certificate" is set to "Always Trust."

7. Close the certificate window, and you might be prompted to authenticate with your Mac password.

8. Restart your Xcode or any relevant applications, and try adding your Apple Push Services certificate again.

Conclusion

By following the solutions provided above, you should be able to overcome the "Invalid issuer" error with your Apple Push Services certificate. Remember to double-check the validity of your certificate, revoke and generate a new one if needed, and ensure the Apple Root Certificate is trusted.
