Struggling with ERROR 400 on EPFO e-sign Registration? Let's Figure It Out Together

Hi Friends,

While going for the registration of e-sign in the EPFO portal under Establishments > DSC, it asks for Aadhar details to generate an OTP. However, when all the details are entered and the "Generate OTP" button is clicked, an error message is displayed. The error message appears as "ERROR 400 BAD REQUEST."

What does the above error mean, and how can I register an e-signature?

Thank you,

Below DSC, one more row exists for e-sign. You have to enter details there. Aadhar number needs to be linked with the mobile number.
