Hi Subhrakanta,
If it is an EPFO portal, there is some problem with system settings and JAWA version installation. Check whether the status of DSC is active or otherwise. If it is deactivated or auto-rejected for some reasons, you have to get it re-registered. Once it is re-registered, a letter will be generated in PDF format. You have to take out the printout of the letter and send it to SRO for approval. In this regard, kindly go through the recent guidelines from EPFO.
Good day,
Sreedhara Murthy
