What does "RMS:Blocked for OPTSTK MKT nse_fo broker" mean

I tried to sell an option, it got rejected and showed a message "RMS:Blocked for OPTSTK MKT nse_fo broker- ZERODHA Remarks: Option Stock market orders are not allowed block type: ALL"
What does it mean?
Only I’m not eligible to sell or it is blocked to all?
