The URL would look like the following:
[hostName] - This should be replaced with your domain or IP address for GoAnywhere Services.
[:portNumber] - If you are using an IP address and the Web Client is not using the default port 443.
[relativeFilePath] - This is the file path once the user logs in. If they have file.txt in their home directory the relativeFilePath would be 'file.txt'. If the file is in a subdirectory like 'outbound' the path would be 'outbound/file.txt'.
[?u=userName] - If you decide to pass in a user name the login page will only prompt the user for a password. Without this parameter the login will ask for user name and password.
