Hi all,

I am about to configure custom domain in my app. Domain is already verified and i am able to show universal login with it. However with the custom domain, universal login is just returning 404.

Has anyone experiened something similar?

Any tips would be greatly appreciated. Thanks!

Hi @onur1,

Welcome to the Community!

It looks like you might be using the Classic Universal Login with the Lock template. When you’re using a custom domain with a customized universal login, you will need to set the `configurationBaseUrl` and `overrides` options like so:

```auto
var lock = new Auth0Lock(config.clientID, config.auth0Domain, {
  //... other configs
  configurationBaseUrl: config.clientConfigurationBaseUrl,
  overrides: {
  	__tenant: config.auth0Tenant,
  	__token_issuer: config.authorizationServer.issuer
  },
});

```
