Page is not open with a domain url set in React default page

[rcbandit111]

I have a React FE app which I run using the default localhost:3000 url address.

When I change the default url to a custom domain and upload it on nginx I get into Spring authorization server only this: GET http://111.111.111.111:30121/.well-known/openid-configuration

Payload:

{"issuer":"http://111.111.111.111:30121","authorization_endpoint":"http://111.111.111.111:30121/oauth2/authorize","device_authorization_endpoint":"http://111.111.111.111:30121/oauth2/device_authorization","token_endpoint":"http://111.111.111.111:30121/oauth2/token","token_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt","tls_client_auth","self_signed_tls_client_auth"],"jwks_uri":"http://111.111.111.111:30121/oauth2/jwks","userinfo_endpoint":"http://111.111.111.111:30121/userinfo","end_session_endpoint":"http://111.111.111.111:30121/connect/logout","response_types_supported":["code"],"grant_types_supported":["authorization_code","client_credentials","refresh_token","urn:ietf:params:oauth:grant-type:device_code","urn:ietf:params:oauth:grant-type:token-exchange"],"revocation_endpoint":"http://111.111.111.111:30121/oauth2/revoke","revocation_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt","tls_client_auth","self_signed_tls_client_auth"],"introspection_endpoint":"http://111.111.111.111:30121/oauth2/introspect","introspection_endpoint_auth_methods_supported":["client_secret_basic","client_secret_post","client_secret_jwt","private_key_jwt","tls_client_auth","self_signed_tls_client_auth"],"code_challenge_methods_supported":["S256"],"tls_client_certificate_bound_access_tokens":true,"subject_types_supported":["public"],"id_token_signing_alg_values_supported":["RS256"],"scopes_supported":["openid"]}```

The page is blank when I open it. I added this Spring Authorization Server client configuration:

@Bean
@Primary
public InMemoryRegisteredClientRepository usersRegisteredClientRepository() {
    RegisteredClient tokenExchangeClient1 = RegisteredClient.withId(UUID.randomUUID()
                    .toString())
            .clientId(clientId)
            .clientSecret(passwordEncoder().encode(clientSecret))
            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
            .authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
            .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
            .scope(OPENID)
            .scope(PROFILE)
            .scope(EMAIL)
            .scope("offline_access")
            .redirectUri("http://localhost:3000/dashboard")
            .redirectUri("http://localhost:3000/sign-in")
            .redirectUri("http://mypublicdomain.com/dashboard")
            .redirectUri("http://mypublicdomain.com/sign-in")
            .clientSettings(userClientSettings())
            .tokenSettings(userTokenSettings())
            .build();

    InMemoryRegisteredClientRepository registeredClientRepository = new InMemoryRegisteredClientRepository(tokenExchangeClient1);
    return registeredClientRepository;
}

Do you know what check is not passed and what might be wrong?
