PayPal IPN to a Worker always 403
HI，I am using cf worker as a PayPal IPN. Recently I have been seeing lots of 403 errors. My domain was set tls 1.2 as minimum level and 1.3 supported. Besides, I have added IP ranges of PayPal to my WAF. Two Days ago it still worked, and now the error occurred again. I wanna know if you have met the similar issue and what is the solution?:NotLikeThis:

There should be more than these requests but now only these 3 can be seen. I have asked paypal they said their service is all fine.
