i have a server and it has installed CSF (firewall). I run docker in the server and the docker-CSF config is enabled, I can reach the containters via nginx reverse proxy.
But i have a problem, the container cannot reach external urls, ex: google.com or facebook.com
When a task inside docker try to consume a external url, I got and error, like the next: Failed to open TCP connection to graph.facebook.com:443 (getaddrinfo: Try again)
How can i fix that? maybe a I need to add an extra rule to the CSF?
thanks in advance
