Certificate signature verification Failed

This has been resolved now having worked directly with their support reps and successfully updated my CSR from Intune.

Same error here when trying renew and create new certificate.

Same issue here when trying to renew any certificate in different Apple Push Certificates Portal accounts and using different MDM CSR to generate the CSR file that is giving the "Certificate Signature Verification failed". When last used less than 1 month ago it was working properly.

Hi everyone, have just seen this update in Service Health in my Microsoft admin center in case this helps anyone who hasn't heard any updates. Issue ID is IT772506.

Title: Admins can’t create or renew Apple Push Notification Service (APNS) certificates

User impact: Admins can’t create or renew APNS certificates.

More info: Admins are unable to create or renew APNS certificates from the Apple device management site, which is accessible through the Microsoft Intune admin center.

As a result of this issue, admins can’t enroll new iOS devices, and any existing APNS certificates that expire will result in device check-in and enrollment failures for those users.

Current status: We are continuing to work with Apple to determine the root cause of the issue. In parallel, we've identified a misconfiguration that could be leading to impact, and we're in the process of testing a potential fix.

Scope of impact: Your organization is affected by this event, and any admin can’t create or renew APNS certificates.

Apologies I won't still be logged in to work at 10pm but I'll update again in the morning here 🙂

I had the same issue when renewing my MDM Cert on APNS over the last few days. I have just retried and am now able to renew this successfully.

Same...any solution? something's changed.

Same issue here, i have send a mail to apns_programs@apple.com

Same here!

Affecting our Org too. I have a case with Apple and they're investigating, but not confirmed yet that it is affecting others.

I got this reply :

I would like to let you know that we are aware of this situation and our

technical team is working on it.

Same problem, Looking forward to further updates.

Same problem here for different customers (all on Intune right now), help would be appreciated.

I am trying to upload csr from JumpCloud and Intune and getting same error. I have Mac devices that are uninstalling software because this has expired, its an absolute nightmare.

Same here..
