Depending on which additional programs you install, you may need to adjust the firewall to allow these services to work as intended. UfW comes with a number of rules already pre-configured. For instance, to allow <app>SSH</app> connections, enter <cmd>sudo ufw allow ssh</cmd> in a terminal. To block ssh, enter <cmd>sudo ufw block ssh</cmd>.
