We have a desktop application which resolves a random port, and uses it each time it calls login, to extract the token, and on logout to confirm successful browser logout. We have configured an open id application for this client app, with redirect uri, and post logout redirect uri (http//:127.0.0.1).
After upgrading from abp 8.2.2 to 9.1.1, login still works fine, howeover, logouts started coming back with 400 response code. Logs show the post logout redirect uri was rejected. Logging in/out using the portal still works fine.
OpenId Application Post LogOut Redirect Uri: http://127.0.0.1 Http Request post_logout_redirect_uri: http://127.0.0.1:31270/ Response Code: 400 Issue From Logs: The end session request was rejected because the specified post_logout_redirect_uri was invalid: http://127.0.0.1:31270/.
