Why am I seeing “Invalid App ID” while connecting Fyers to uTrade Algos?

This occurs when your browser has an active Fyers session that conflicts with the account you are trying to connect.

It usually happens if:

A. You are already logged into a different Fyers account in the same browser.

B. You switched Fyers accounts without logging out first.

C. The login redirect flow was interrupted.

How do I fix it?

  • Log out from the Fyers website completely, and then try to relogin in a fresh browser window.
  • If the issue continues, use Incognito/Private mode, clear cookies for fyers.in, or try connecting from a different browser.
