Getting "invalid request" error for https://api-t1.fyers.in/api/v3/token

Request is: https://api-t1.fyers.in/api/v3/token, fyers id=<abc>, pan_dob=<abc>, app id=<abc>, redirectURI<abc>, appType<100>, code_challenge<>, state<state>, scope<>, nonce<>, response_type<code>, create_cookie<true>

Response is:

{protocol=h2, code=400, message=, url=https://api-t1.fyers.in/api/v3/token}, error {"code":-441,"message":"Invalid request","s":"error"}, request data - url

This is happening for last 3/4 days. But after couple of attempts, this REST endpoint used to succeed and then there wasnt any issue till the session ends. But today, its continuously failing.

Since migration to V3 (more than year back), this code used to function absolutely fine.

Any idea whats the issue?
