Trunk not getting registered

Hi, i am using Asterisk 11 and Freepbx verison . I created a trunk yesterday to test IVR and extension via a DID. It worked fine but today on same settings, trunk is not getting registered. Here is my config for trunk :

host=sip2sip.info
username=param90
secret=xxxxxxxxxx
type=peer
allow=ulaw
disallow=all
context=from-trunk
insecure=invite

Register string

param90:[email protected]/253xxxxxxx

This is massage i am getting in server logs

Registration for ‘[email protected]’ timed out, trying again (Attempt #1),
it keeps on attempting . Yesterday it worked fine and trunk got registered but today on same settings, it’s not working. I am new to asterisk and freepbx. Please help

Did You try to connect to this trunk with a softphone?
Try that, so You can bu sure if they dont have any problems/issues
Also i would check if pbx has internet connectivity.
