Http, https proxy - When there is no direct Internet connection

Can you please tell me if it is possible to redirect all requests through http, https proxy.
My server does not have a direct connection to the Internet and should not.
Incoming connections work through haproxy on a separate server.

n8n does sadly have nothing like that build in. But you should be able to use the environment variables HTTP_PROXY and HTTPS_PROXY for outgoing calls as n8n uses under the hood the request library which supports them.

It works, thank you.

Great to hear. You are welcome!

Have fun!
