Facing issues in clearing my holding

I am facing some issue when I am trying to sell my holdings, the TPIN is generated but then it shows an unexpected response and 502 gateway error

This was message from Zerodha: The CDSL TPIN authorisation service for selling stocks is having issues intermittently. CDSL is working on bringing the service back up soon. This was a new regulatory requirement from today for non-POA customers (accounts opened post-Nov 2019).
