The TFTP protocol has *NO* security, so changing the root folder to a 
subdirectory your home directory is *NOT* a good practice.

The tftp server very likely doesn't have read permission to read the 
directory you set it to.  Your /home directory is probably not 
world-readable.  Setting it to be world readable is not a good practice. 
  This will probably "fix" your problem, but IS A BAD PRACTICE:
   chmod -R o+r /home/haustiq

You need to configure your tftp server properly.
