One of our users reports that when he uses Chrome to access our web site, he is blocked with a CloudFlare “1020” error. But when he uses FireFox, he can access our web site without problem.
The user is a network administrator for a utility company. So far as I know, he is not a bot.
I looked up the RayID on the Firewall Overview page and the rule name is “manage definite bots”
But on the Firewall Bots page, filtering the by blocked IP address, the traffic is identified as “likely human”.
Why is “likely human” traffic blocked?
Why is the user blocked when using one web browser and not another?
Our Super Bot Fight Mode is configured as follows
Definitely Automated: Block
Likely Automated: Allow
Verified Bots: Allow
Static Resource Protection: Off
Java Script Detections: On
