MDM CSR - Invalid CSR

Hi All,


My question pertains to uploading an MDM CSR via the Apple Developer Program to obtain an MDM certificate. We have a .Net application that we use to create the MDM CSR (in the form of a text file). When uploading the CSR, we now encouter the error "Invalid CSR - Select a valid Signing Certificate request". This used to work. I have also tried creatying the CSR directly from with IIS, but the same error occurs. Have the Apple requirements changed in the last few months? Our wwdr certificate is current.


I created the CSR from my Mac (.certSigningRequest) and this works without issue. I compared the CSR's using Symatec's CSR checker. The certificate information is identical (Signature algorithm, Key algorithm, Key size).


Has anyone recently been able to upload a CSR created in IIS? What has changed?


Thanks in advance,


Shawn S.
