Hello, I am Sergio Sánchez, administrator of NumbuX.
We are developing our own MDM. We are already granted as a MDM Vendor. We need to issue the APNs certificate for our MDM for the first time in the Push Certificate portal (identity.apple.com).
We are having the error: “invalid signing request” when we upload the signed CSR to identity.apple.com. That is because we do not have the External UUID.
Could you please let us know what is our External UUID? Without that, we cannot upload it successfully.
We have already compared different signed CSR from other MDM Vendors and all have included the External UUID in the CSR.
Please, do not send links, there is not way for us to know our External UUID because it is the first time that we try to issue this APNs. After the first time, we do not need your assitance.
Please, let us know our External UUID.
Thank you.
Kind regards.
