DSC verification error in Form LLP-4

[Parbat Chaudhari]

Dear Members,

I am filing Form LLP-3  and Form LLP-4 for change in designated partners.

After affixing DSCs, while uploading the Form LLP-4, the same is showing error that - digital signature verification failed, affix a valid DSC.

I have tried to edit the form and submit old forms, tried from every browsers etc.

Please suggest how to resolve this issue.
