Configuring an FTP server
Enter the hostname and port your FTP server is listening on (if you haven't changed this you can leave this field blank and DeployHQ will use the default port 21).
Enter your username and password, then enable passive (PASV) mode if your server supports it. Finally, if your FTP server doesn't report hidden files such as .gitignore by default, you can enable the option to Force the server to report hidden files.
If you're seeing a certificate/SSL error whilst trying to add your FTP server, it may be worth trying to connect via FTPS instead, as your server may not allow insecure logins.
