With my host, i can see i have a lot of OUTGOING CONNECTION to cloudfare while i don’t have any cloudfaire account.
The IP is : 220.127.116.11:443
And here : https://dnslytics.com/ip/18.104.22.168
We can see it is Cloudfare
Could you tell me how to shop these outgoing connections ?
You will need to check in your code where that connection originates from. That would be a bit off-topic for this forum.
Where can i ask my question ?
Either whomever is responsible for your server maintainance or - if that is you and you need further hints - at a forum aimed at system administration. Stack Exchange maybe.
