Error getting more details Wordpress plugins info

Hello

first of all, sorry if i post in the incorrect category.
I configured CF, only with certain firewall rules, security headers with workers and when CF is active and i try to get more information in each plugin, “see details” inside wordpres dashboard, appears the message: “domain.xxx has rejected the connection”
If i stop CF, works fine. I reviewed all entire CF config, but i can´t see where is the problem. Nothing appears into CF logs blocking this connection.

Does anybody know what is the problem? Obviously in my CF configuration :smiley:

Thanks in advance
