Auth0 Home Blog Docs

The client was not found: undefined


Using ws-federation. After the first login, if the redirect happens again I get the error:

invalid_request : The client was not found: undefined

If I remove the “auth0” cookie that is set for my application domain (i.e., it starts working again.


Hey there @darren.gillis!

I’m not sure if I understood you correctly. So you are able to login for the first time and then if you log out and want to log in again you get such error, is that correct? Thanks for providing a few more words for clarification!


Hi @konrad.sopala,

There was no explicit log out action. The client application browser closed and so the cookie stored locally for the client app expired and so on next client login, the redirect takes place over to auth0 and this is when the error occurs.


Thanks for clarifying that! That is quite unexpected. Have you got such behaviour after following tips from our content on setting up ws-fed?


Hey there Darren!

Have you managed to solve the issue by now or do you need any further help?
