Which one should I use? * Most people should try the SSL/TLS connection first. This method should work for 99% of modern devices. * Some country/state/company firewall blocked one or the other ports. Some software/device/versions has "bug" in one or the other connection methods. That's why people invented different workaround methods. Please try other methods if SSL does not work for you.
