Anti-DDoS Recaptcha Not Working - Openlitespeed

Can't get Recaptcha to activate.
It worked fine for me on LSWS but Openlitespeed isn't working
Tried adding a specific rule to htaccess as well which didn't help

I've also tried both invisible and checkbox.
Neither options worked
It just keeps throwing 403 errors when I get ddosed and blocking legit traffic

The "Checking if you're a robot" never appears
