I am currently testing an app in TestFlight and need a production APNs certificate in order to test Notifications in Firebase.
I have followed all of the steps in this video and successfully configured the development APNs certificate: https://www.youtube.com/watch?v=LBw5tuTvKd4
I've also checked that my steps following the Firebase support guide. Although I note that the Apple Developer site has changed slightly since this guide was written: https://firebase.google.com/docs/cloud-messaging/ios/certs#configure_an_app_id_for_push_notifications
I have generated a production APNs certificate at developer.apple.com using the same method as the development certificate but when I try to upload the .p12 file to Firebase, it gives me the following error:
"The certificate environment did not match. Ensure that you got the right development or production APNS certificate."
I'm definitely uploading a .p12 generated from a production APNS certificate, is there something else I need to do for a production certificate?
Solved. The mistake I was making was that I was exporting the "private key" part of the certificate in Keychain Access instead of the "certificate" part. As soon as I re exported the .p12 using the correct row in the list - it worked.

Correct method:
try this
make .csr file and download cert from developer.apple.com
while exporting select private key and certificate both at a same time and export to .p12 with any passphase.
upload tht .p12 file on firebase console.
Thanks
I am facing the same problem and i have tried all above mentioned solution but nothing works for me than i delete certificate from keychain access and again download certificate and install it than export and try to upload it. It works for me.
Don't select private ket in key chain, directly select certificate and create production certificate.
1) Don't select private ket in key chain.
2) Directly select certificate and create production certificate
When I tried the solution suggested here, nothing works (This probably means I am doing right). I solved this issue by replacing Chrome (The application is running for a very long time) with Safari (I invoke the application just for this purpose) for the upload.
That means, if restart Chrome might also work.
FYI.
In my case I wanted to upload a production certificate to Firebase, and after trying everything I finally realized that I had created a development certificate on iOS Developer...
There might be an inssue of semantics in some cases, so pay attention to meaning.
When you have to upload the certificates in firebase console there are 2 boxes with placeholder text which read:
1. No development APNs certificate
2. No production APNs certificate
In my case, I had understood that I must not upload a development APNs certificate in box 1. Actually, firebase meant that no development Apns certificate has been uploaded yet and that I could upload my certificate.
