Cand post google analytics code to my website (get blocked)

Hi,

I am trying to post a simple google analytics code in the settings area of my website. But cloudflare is denying and blocking my request.
I have tried creating a page rule to bypass the security rules from my IP and have added my IP4 and IP6 ip adresse into the rule. But i still get blocked by cloudflare. How can i temporary create a rule for me to bypass this so i can post the code to my site?

In my event log i see that its this rule which blocks it
