My settings are these: ° keycloak radius plugin installed quarks. (ubuntu 20.04.3) ( external server ) running: /opt/keycloak-radius# bin/kc.sh start --hostname=mydomain.cloud --hostname-strict-backchannel=true --https-port=8443 ° configured https tls and hostname external ip ( no proxy ). ° radius over TLS configured as radsec port 1812 ,1813. ° configured "mikrotik-radius-plugin" only for login mikrotik ° user created for login test

My Mikrotik ° Routerboard RB750GR3 version 6.49.6 (stable) ° configured radius radsec, accouting AAA

The mistake: when i go to login by winbox i get the following error in keycloak terminal.

STATUS RADIUS ROUTERBOARD

I don't know where I'm going wrong.

I have same problem :(

I just solved it by doing a fresh install
maybe to some configuration that I went wrong

the problem may be involved in the radius authentication issue
radsec or udp protocol.

I still have this problem even fresh install with maven or docker. Can you write a guide for install and config keycloak and mikrotik?
i have error when create new client with client type radius-protocol

I found out that we need to use realm id instead of realm name

I just export realm configuration to get id

and paste it to MikroTik radius Realm field
