Hi @odommo, thanks for your message.
Could you please try switching the Wordfence Firewall into Learning Mode to see if it catches the requests and allows them?
From the Wordfence Dashboard click on Manage WAF. Then you will see Basic Firewall Options > Web Application Firewall Status. Change the option to Learning Mode. Now perform some actions on your site that will trigger RankMath activity, including using the administration pages if applicable. This will help Wordfence learn that these actions are normal and it will allow them in the future. After you have finished, switch the WAF from Learning Mode back to Enabled and Protecting. Now test to see if RankMath continues to collect data correctly.
https://www.wordfence.com/help/firewall/learning-mode/ is an amazing resource for learning more about the WAF and learning mode.
Let me know how it goes!
Peter.
