SmartCrawl is running forever

Samrtcrawl was runing on my site. But after facing some issues with the hub I've lost the config.
When I run an analysis the scan run forever and never end (last week from now scaning)
I found there is a conflict with Wordfence that was previously solved but is back again:

BACKGROUND REQUEST BLOCKED

Wordfence Firewall blocked a background request to WordPress for the URL /wp-admin/admin-ajax.php. If this occurred as a result of an intentional action, you may consider whitelisting the request to allow it in the future.

I would really apreciate if you can check it
Thanks
