Error 403, cloudflare block my moodle

Good day, I have moodle hosted on azure, with DNS generated by azure, linked to a third party subdomain, through a cname and with an SSL issued by Go Daddy, and I receive block messages from Cloudflare, checking the inspector I see that specifically

/lib/ajax/service-nologin.php

and the block page sends me this link: Cloudflare Ray ID: 733fbd76bed64ffa

I have been told that it is due to the OWASP rules and they are set at 40 points and my Moodle exceeds that value. What can I do in moodle or my server in azure so that Cloudflare does not block me. In fact, if I access from the DNS provided by Azure, everything works perfectly. Please help
