Hello @Ankita_1 ,
Each certificate has approx. 20MB. It’s quite a lot for a .pdf file.
In my case, I’ve clicked to download the certificate, wait for 4-6 seconds and cancel the request.
Afterwards, I’ve waited for another 40-50 seconds and, tried again to download the certificate. This is how it worked in my case.
Please make sure that your internet connection is a good one. Avoid the rush hours.
Best regards,
Marius
