HTTP Proxy
If your computer uses a HTTP proxy, you will need to specify the details for TileMill to work correctly. The proxy details need to be entered in the form of http://user:pass@hostname:port
where user, pass, hostname and port are replaced with the relevant proxy details. After entering and saving this setting, you will need to restart TileMill. You should then be able to make use of TileMill’s features requiring network access.
Note: TileMill does not support proxies for authorization. To authorize, open http://localhost:20009
in a browser after starting TileMill.
