Failed to turn code into token (with 403 error)

Hello everyone,
When a user tries to connect to my app some users reported that they “sometimes” face this “failed to turn code into token” Error some times (I couldn’t find the exact scenario)
which leads the user to an error page with code 403.
And when they refresh the page the error disappears and they get redirected to the app.

Can anyone tell me what are the possible causes of this error, and how possibly can fix it.

PS : I’m using OIDC v1.0 as IdP.

Thanks in advance :slight_smile:
