The <code><span style=\"color: #048eb0;\">PORT<\/span><\/code> needs to be replaced with a port number depending on the service you are going to test:<br \/>\nPort 21 \u2013 used for FTP;<br \/>\nPort 25 and port 587 \u2013 are used for SMTP, SMTP+TLS, and SMTP+SSL;<br \/>\nPort 80 \u2013 used for HTTP;<br \/>\nPort 443 \u2013 used for HTTPS;<br \/>\nPort 110 \u2013 used for POP3 and POP3+TLS;<br \/>\nPort 143 \u2013 used for IMAP and IMAP+TLS;<br \/>\nPort 993 \u2013 used for IMAP+SSL;<br \/>\nPort 995 \u2013 used for POP3+SSL;<br \/>\nPort 2222 \u2013 used for SSH.<\/p>\n<p>So for example if you experience problems with HTTPS access on a domain named yourdomain.com, you need to execute the following command:<br \/>\n<code>telnet <span style=\"color: #048eb0;\">yourdomain.com 443<\/span><\/code><\/p>\n<p>For some Windows versions you need to explicitly enable Telnet, you can find out how to do this using the official tutorial from the Microsoft Wiki -&gt; http:\/\/social.technet.microsoft.com\/wiki\/contents\/articles\/910.windows-7-enabling-telnet-client.aspx)<\/p>\n<p>If you connect successfully you should receive either a blank screen or a server response stating the name of the service.<\/p>\n<p>If you cannot connect to our servers, you should receive an error like this:<br \/>\n<code>telnet: could not resolve <span style=\"color: #048eb0;\">HOSTNAME<\/span><\/code>\/<code><span style=\"color: #048eb0;\">PORT<\/span>: Name or service not known<br \/>\n<\/code>In the latter case, please try using Telnet for another port on our servers as this will help you to determine whether our firewall is blocking your IP address or the problem lies elsewhere. If you cannot connect through another port, please open a Trouble Ticket concerning the problem from your Hosting Control Panel -&gt; Support -&gt; Support Center -&gt; Trouble Tickets, so our Support team can investigate the issue and check if we are blocking your IP address for some reason. If you can connect through another port, this means we are not blocking your IP address and something is restricting the connection. A few things that could be blocking the connection are \u2013 the firewall of your local computer, the anti-virus software of your local computer, the local router, and your ISP.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Telnet allows you to see if you have \u0430 connection to a specific hostname on a given port.
