'"Unexpected error when authenticating with identity provider" error when Keycloak broker is configured as a client to another Keycloak instance

I am getting an error when I try to login to Keycloak by using it as a broker.1 I am using credentials from another keycloak instance to login. So far, I am redirected to the correct login page but after entering my credentials I receive an error.

I have set up Keycloack Identity Brokering on computer 1 by following the basic steps.2 I have used the generated redirection URI of the broker to register a new client on computer 2 in another Keycloak instance.3 The client configuration present on computer 2 4 is then used to fill in Authorization URL, Token URL, Client ID and Client Secret on the Identity Broker on Computer 1. 5

I may be leaving important fields missing. Pictures are attached for reference.

I have changed some settings to get the broker to work with the other Keycloak instance. I am now sending client secret as basic auth with signed verification off. I have also enabled back-channel logout. Hope this helps someone else.

In my case I needed to empty the hosted domain field in the "Identity providers" configuration of my Google identity provider in Keycloak.
