Reverse ip fails

[lamadremantia]

URL error, [Errno 111] Connection refused
Traceback (most recent call last):
  File "sqliv.py", line 117, in <module>
    domains = reverseip.reverseip(args.target)
  File "/root/sqliv/src/reverseip.py", line 43, in reverseip
    obj = json.loads(result)
UnboundLocalError: local variable 'result' referenced before assignment

That's because reverse ip site (domains.yougetsignal.com) gives a Forbidden error.
