I already installed discourse in a server behind a firewall. And an HTTP proxy server was set up by
export https_proxy=http://192.168.1.2:3128 export http_proxy=http://192.168.1.2:3128
But I found that the email sending function is not ok. It’s always timeout, so, I guess it caused by the network setting.
Thanks for your time to read my issues. Any hints are very appreciated.
