If the requests trigger the Managed Rules, if you’re on a Free plan type, you can only add the IP Address(es) to the WAF → Tools → IP Access Rules with the action “allow” for your Website.
Otherwise, if you’re on a paid plan type, you can add an Exception Rule for the specific ruleID or rulesetID which you can determine by checking the triggered service and Security Events under the Security tab.
You should be able to see the challenged or blocked event under the Security tab → Events at Cloudflare dashboard for your zone and know exactly which security option was triggered.
Once you find them, click on a particular one to find more details about it (user-agent, IP, HTTP version …). If yes, could you share some details which service was triggered that blocked you?
