Google Apple Push Certificate expired

I am trying to enable iOS device management.  For that Google says that I need to setup an Apple Push Certificate.
Apple says the Google certificate is expired!
- in Google Admin I do: Device management -> Mobile -> Set up Apple Push Certificate
- download the file google_ios_push_certificate.csr
- sign in to Apple Push Certificate Portal and select to "Create a New Push Certificate"
- I then upload the file above as requested
--> Apple responds "Certificate Signature Verification failed because the signing certificate  is expired."

So how do I get a valid certificate?

Thank you.  But the "Manage Apple Push Certificate" is not an option under Mobile Management -- the only options are "Device management settings", "Device activation", "Managed devices", "Set up Apple Push Certificate" (what I use to start with) and "Set up Android for Work".
Probably because it is the very first time I try to connect an iPhone to this account.
Any other thoughts?

Can you post a screenshot of the set up apple push certificate screen?

I ran the exact same steps as yesterday (this time taking screenshots) and strangely, this time the Apple Portal accepted the freshly downloaded google_ios_push_certificate.csr
All I can think of is some issue with date/time stamps between Apple and Google between 6/30 and 7/1 (end of month?).
Thank you for your help

I solved the problem myself by rerunning.  But the hint was relevant enough to prompt me to retry.
