EPF Error while approving KYC pending for DSC - also not receiving the Email confirmation from EPF to authorize the Email

Hi, Please find attached the error report getting while approving Employee's Approve KYC pending for DSC. While I had generated and submitted Authorized Signatory information with EPF office through Speed post on 06.03.2021. Kindly guide me as to how to overcome this problem.
Secondly, I am not receiving the Email confirmation from EPF to authorize the Email. Could you please throw some light as to how to get it done?
Thanks in advance

Dear Mr Ravi,
Pl log in to Employer Portal & verify whether DSC is active? you have sent the Document by Speed Post.Whether PF Office has approved your DSC.If not, send E-Mail for activation of DSC based on your Document
