In Azure ADB2C the final Step to exchange token is failing

Suresh 0 Reputation points

I have a custom policy .. My Login Works and I am sucessfully able to authenthicate against my ID . However in my last step of the process where postman makes a call to getToken , I get a 504 gateway time out

In the Azure AD Audit Logs i get this error which says this .. What am I missing and why is it failing

I am pretty sure it is in the JWT Issuer area .. not sure where it is going wrong .. Any Help would be greatly appreciated

I am using Code flow for the app I have registered
