crawl/URL's to Scan error

Jonathan Fine Jul 30, 2019 04:14PM UTC

I'm having an issue (or is it a bug) whereby I have a website on a domain that has an underscore (for example,, but setting up a crawl scan type gives me 'Invalid URL to scan' error despite the site working through the proxy.

Anyone else run into this?

The _ character cannot be used in a domain name.

The _ character can be used if it's a cname

Jonathan, as this is not a valid domain name we don’t support this.

As a workaround, please add a record to your hosts file without an underscore to resolve to the site’s IP address.

Please let us know if you need any further assistance.
