Dear sir

Problem 1
I am trying to update my aadhaar kyc on uan but every time it gives error that "server has problem, please try after sometime". Let me know how to do kyc aadhaar on uan site.

Problem 2
I have downloaded the epfo app and trying to link with uan no and aadhar no, the aadhar verification done with the otp, when i am proceding towards the uan and aadhar linking and generating the otp for that i am facing the issue with

Asa006: request xml signature varification failed

Invalid key info in digital signature (This means that certificate used for signing the authentication request is not valid - it is either expired, or does not belong to the aua or is not created by a well-known certification authority).

Problem 3
I am unable to update pan details on uan portal. Each time while i enter the details it shows error as error while pan authentication failed. Name mismatch. Please suggest

As nobody responds at epfo customer tollfree no
