Error "Web UI: Unable to bind to IP: 42, port: 8080. Reason: The address is not available" at start with clean install without configs.

Extra info

If we look at https://github.com/qbittorrent/qBittorrent/blob/master/src/webui/webui.cpp#L96-L97, we can see "*" (asterisk) used as a default bind IP. And asterisk's ASCII code is 42. I think there's automatic type detection problem somewhere. Also, if we look at documentation, QHostAddress::Any is enum and not QHostAddress or string. Shouldn't code above

            const auto address = (serverAddressString == "*" || serverAddressString.isEmpty())
                ? QHostAddress::Any : QHostAddress(serverAddressString);

be like

            const auto address = (serverAddressString == "*" || serverAddressString.isEmpty())
                ? QHostAddress(QHostAddress::Any) : QHostAddress(serverAddressString);

instead?

Workaround

Add

WebUI\Address=*

to .config/qBittorrent/qBittorrent.conf
