Want to relay, but 443 is bound by different app
Thank you for (trying to) run a relay! Something on your computer is using port 443, so Tor cannot use it. Please choose a different port for Tor. Skype is a popular example of a client software that uses port 443. If you want, you can identify the process using a free tool from http://www.nirsoft.net/utils/cports.html (Windows).
