Too many redirect - AuthorizeNonce cookie didnt match the nonce in authorizeState

[jamesy829]

When I use the suggested way of configuring all web apps to forward /oauth2 path to ForwardAuth (thread), the error I get is 400 Bad Request AuthorizeNonce cookie didnt match the nonce in authorizeState.., it then starts another Authorization Grant all over again, at the end Chrome will show ERR_TOO_MANY_REDIRECTS

I am currently running Traefik 2.9.6, deployed with Helm charts and the stripprefix and redirect are implemented using middlewares (thread)

This is my application.yaml

 domain: https://mydomain.auth0.com/
 token-endpoint: https://mydomain.auth0.com/oauth/token
 authorize-url: https://mydomain.auth0.com/authorize
 userinfo-endpoint: https://mydomain.auth0.com/userinfo
 logout-endpoint: https://mydomain.auth0.com/v2/logout

 default:
     name: mydomain.com
     client-id: <CLIENT_ID>
     client-secret: <CLIENT_SECRET>
     audience: https://mydomain.com
     scope: "profile openid email"
     redirect-uri: https://auth.preprod.mydomain.com/signin
     token-cookie-domain: mydomain.com

 apps:
    - name: traefik.prep.mydomain.com
      required-permissions:
        - read:traefik
    - name: epimetheus-preprod.mydomain.com
      required-permissions:
        - read:epimetheus

This is my middleware

This is the version of docker I'm using.

Figured out it was a typo within the yaml
