Reindex Table not working

Hello

“reindex table” on my ad. woo search is not working, it’s always on 0%. At first it was anyway adding products but now it stopped at 705 products and won’t add more. The error that I am getting in console is:
{“success”:true,”data”:”Deleted!”}
and
{“wp-auth-check”:true,”server_time”:1513766312}
and several more server_time as it goes on.

Regards,
Momir
