I want to use HTTPS push notification. So I purchased SSL from GoDaddy (Go Daddy Class 2 Certification Authority Root Certificate, https://certs.godaddy.com/anonymous/repository.pki). I've certificates in .CRT & .CER (DER
Format) format. I tried to upload on Dev Center but it's saying "Make sure the certificate is correct and then try uploading it again." I also tried to upload .CER (Base-64) format by exporting the certificate, it didn't worked. I also tried
to upload in .PEM format using
SSL Converter it didn't work.
So can anyone guides me what's the correct way/format to upload the certificate.
