Access_denied 403

I built in Auth0 to single page application.
I could signed up without problem, but I couldn’t login this account for the following Error
status code:403 access_denied.

my application work on http://127.0.0.1:8100 so I input http://127.0.0.1:8100 in the Allowed Callback URLs field.

I’ll appreciate if someone could give me some advice.

Hi stando,

I would start with the logs:
https://manage.auth0.com/#/logs

Hi Jone,

Thank you for your advice.

My app Failed by CORS

“description”: “Origin http://127.0.0.1:8100 is not allowed. Behavior used for check: WEB ORIGINS”

Do you know what I should do to solve it??

Hey there @stando! Do you have URLs populated in both the app’s Allowed Web Orgins and Allowed Callback URLs? Here’s a doc that dives into setting up a web application in Auth0. Thanks!
