[keycloak-user] Error when using https

I have the below keycloak-gatekeeper config that works fine. However when I switch "discovery-url" to my https domain: "discovery-url: https://sso.mydomain.live/auth/realms/myrealm" I get the following error after I login with keycloak-gatekeeper "unable to exchange code for access token {"error": "mime: no media type"}" The discovery URL is the only thing I am changing. When I go to " https://sso.mydomain.live/auth/realms/myrelam/.well-known/openid-configur... I can see all the same information that I see when i go to " http://192.168.1.164:8080/auth/realms/myrealm/.well-known/openid-configur... " Anyone have any clues as to why this isn't working? keycloak-gatekeeper config: discovery-url: http://192.168.1.164:8080/auth/realms/myrealm client-id: my-client client-secret: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx listen: 0.0.0.0:3001 redirection-url: https://test.mydomain.live upstream-url: http://192.168.1.162:8123 encryption-key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx enable-authorization-header: true enable-authorization-cookies: true verbose: true enable-logging: true enable-https-redirection: true secure-cookie: true enable-encrypted-token: true enable-token-header: false enable-refresh-tokens: true preserve-host: true enable-security-filter: true resources: - uri: /*
