Error 404 But Zaraz is on

It´s my first time configuring Zaraz, I´m using the manual script with Proxy enabled.

This is the script I put on the Head HTML on GoHighLevel

Browser console gets 404 error with the script + injection disabled and without it + injection enabled.

Even tried to change the endpoint to another letter but it´s not working.

Please follow the FAQ: FAQ · Cloudflare Zaraz docs

I already did, but I find myself not understanding why isn´t working. Same with Developer Certification Program on YouTube although I´m not a developer.
