I have one extension that simply does not want to register. The username and passcode are correct and I can see the auth challenge in the log but it does not tell me why the registration is failing. I already turned off or restarted fail2ban, iptables and freeswitch just to see if anything changes but the problem continues. Is there any other log I can look at that would provide more information?
