Hi @eazhages,
You have modified a lot of the basic URL configurations compared to the original setup of the sample. It is very likely that your URL setup is not consistent. Please check them again.
Hmm… One thing: why have you modified the spring.security.oauth2.client.keycloak.redirect-uri to the hard coded value http://localhost:7070/app/*?? This way the authentication code from Keycloak won’t reach Spring Security. The original value has been "{baseUrl}/{action}/oauth2/code/{registrationId}". See Spring Security documentation for more details on that. It is highly probable that Spring Security is now unable to continue the OAuth 2 authentication flow. Hence you get the result you have.
Best,
Gunnar
