Bingbot is blocked by cloudflare

am trying to get my site crawled in bing webmaster, but bingbot is blocked by cloudflare
I tried to add rules to all all bingbot user agents that are in this page:
https://www.bing.com/webmasters/help/which-crawlers-does-bing-use-8c184ec0

but it still being blocked, only when disable cloudflare bingbot will crawl.
how can I fix this and allow bingbot without disabling cloudflare?
thanks

From where you saw that Bingbot was blocked?

I have no idea, all I know is it will only crawl if I disabled cloudflare

Have you taken a look at the Firewall Events Log in dash.cloudflare.com? It should show the blocking events and the rule that blocked the request.
