483 Too Many Hops

Hi all,
I am attempting to setup kamailo and keep receiving a "483 too many hops" when trying to register. I'm using x-lite.
My client makes a request to register, kamailio responds with a 401, then my client responds with authentication credentials and then Kamailio responds with 483. I've included below a wireshark of the exhcange.

Thanks in advance.

Check make sure you have added the domains even if you haven't loaded LCR. It's weird but it fixed the problem for me. In fact I had to add two domains.
