Hey everyone. I am working on setting up keycloak in my homelab and wanted to setup google authentication.
Following the doc I set up google oauth consent screen and configure keycloack. I can land on the login page well and can click on my google account to login. However final redirect to keycloak fails with this big error trace
12:48:55,657 WARN [org.keycloak.connections.httpclient.DefaultHttpClientFactory] (default task-1) TruststoreProvider is disabled

12:49:15,836 WARN [org.keycloak.events] (default task-1) type=IDENTITY_PROVIDER_LOGIN_ERROR, realmId=Homelab, clientId=oauth2-proxy, userId=null, ipAddress=10.10.12.48, error=identity_provider_login_failure, code_id=a164fb1f-1509-4250-bf43-6e5577daca9b, authSessionParentId=a164fb1f-1509-4250-bf43-6e5577daca9b, authSessionTabId=eJEhoSKg04s
It points to a DNS error while trying to verify the oauth callback, but I can resolve oauth2.googleapis.com just fine from the container and the host.
Investigating further I check my DNS server logs and see that in fact the container is requesting
oauth2.googleapis.com. instead of the right domain
What is weird is that we have 2 DNS queries with the right domain, and then 2 with the .home appended.

Any idea where I could configure it so that the queries are correct ? If you feel like anything more is needed to debug the problem please let me know how to fetch it. I am running jboss container latest (at the time of writing version 16.1.1).
Thanks for the help
