Need help with computer number

I don't know what this error means. I tried looking online and the answer I got was to send a letter but, there is a new policy on not sending physical documents. I sent [help.pariksha.dgca@gov.in](mailto:help.pariksha.dgca@gov.in) and email with all my credentials for online verification, but it got rejected. DGCA's helpline number no one picks up and no answer to email either. Any advice?
