Hello, Registering a device fails in my test kazoo cluster (3 hosts, first is rabbit). The rabbit.log says that everything is fine (AMQP connections accepted) But kamailio.log says: |log|failed to query registrar for authentication credentials for user_test@xxx.xxx.xxx.xxx (xxx is the ip address) Any suggestions, where I could start to look for? I used this guide for the installation (CentOS-6.7-x86_64 as operating system) https://2600hz.atlassian.net/wiki/display/Dedicated/via+RPM Greets, Andreas
