Current web console domain is not the same to the OIDC callback

If the callback url in RustDesk web console settings http://localhost:8000/#/settings/oidc and your OIDC Providers settings is http://localhost:8000/api/oidc/callback.

Then you cannot login from http://192.168.1.3:8000/#/user/login

How to solve it

1. Change the callback url in RustDesk web console settings http://localhost:8000/#/settings/oidc and your OIDC Providers settings .
