find_domains.py crashes with ValueError: Invalid IPv6 URL:

@megancarney identified that this is caused by a URL similar to "https://example.com/#/discover?_g=()&_a=(columns:!(_source),index:%5Blogstash-%5DYYYY.MM,interval:auto,query:(query_string:(analyze_wildcard:!t,query:'*')),sort:!('@timestamp',desc)), basically sort of URLs that Kibana dashboard produces.

This maybe caused by the same problem as #5.

Closing as it is a duplicate of #5.
