Unfortunately, these errors mean that
1 - you are using an ad blocker like UBlock Origin ( just disable it during a crawl )
or
2 - the website's server has denied access to our crawlers for security purposes.
NOTE: Some sites deploy highly protected security measures to prevent all automated crawlers. Except for Google crawlers.. of course!
If you see this issue, AND you own the site ( or have access to its servers )
then you can try to whitelist our crawler by selecting :
1. Click Advanced Settings > Include Custom ##### HTTP Header
2. this will show your UNIQE header ID.
3. copy/paste that into your server configs.
This will generate a unique header ID *value assigned just to your account/crawlers.
