Registration error 408 in X-lite

I have setup up my first FreePBX (AsteriskNOW) system and I want to make my first call using SIP.
I use the X-lite softphone but I get registration error 408.

You can see the complete configuration of my system at the following pictures:

What is wrong?
Where can I find a simple guide how to use FreePBX with X-lite?

Thanks in advance

I just restarted the asterisk machine and now it works fine.

I had to set my proxy address port to 5060 to make it work.
just rebooting wasn’t enough

After I rebooted (again), I tried removing the port 5060 reference and it still worked.
Maybe two reboots were required.
