Callback exchange failed from PHP SDK with no auth0 live log

Hi All,

I facing random issue with callback exchange failed (Login Issue) message for some specific users (Not for all).

  • We have PHP based application so using PHP-SDK
  • We have organization based login so user is successfully able to enter password and submit the form.
  • Auth0 logs are showing properly for the actions performed
  • But, when it is coming to callback-url, it is throwing error from php-sdk : “exchange_failed”
  • And there is no logs entry in auth0 under monitoring logs.
  • If the user again clicking on login button its redirecting to same page with same message.
  • But if I open the same user in incognito window it works.

Please help me to fix this, Appreciates your help and inputs in advance!
