@dan said in Wrong logout URL being returned ?:

@francis-ducharme What is your setting for logoutBehavior for each application config? All applications or redirect only?

By default it is 'all applications' which means that FusionAuth, on logout, will call each application's logout url (to ensure that the user is logged out of all applications). It does this via an iframe, so I'd expect both to be requested. https://fusionauth.io/docs/v1/tech/guides/single-sign-on#configure-the-applications-in-fusionauth has a bit more.

I'm not sure why you are ending up at localhost for the dev app, though.

That was it. All my application's logout behavior were set to "All Applications". "Redirect" only made it so the browser doesn't get redirected to "localhost".
