It may be on me, but I failed to use oidc-cli because it tries to bind IPv6 address.

$ oidc-cli create public keycloak_pub --issuer http://192.168.1.9:8080/realms/my-realm --client-id my-app
10:19:43 [ERROR] Address not available (os error 99)

I can use it after changing this line:

-       let addr = SocketAddr::new(Ipv6Addr::LOCALHOST.into(), port);
+       let addr = SocketAddr::new(Ipv4Addr::LOCALHOST.into(), port);

It is sad to see that IPv6 still have such paper cuts nowadays. I've enabled IPv6 at least 😝.
Is there any particular reason for using IPv6?
BTW, I'm using Arch.
