More Information About Tcp Connect

The requested TCP address could not be reached.

Additional Information

When the TCP address is checked by our servers, we wait a standard 15 seconds for a response. If we do not detect a response, this error will be triggered.

TCP (Transmission Control Protocol) is a specific way to transmit and format data over a network between two IP addresses, hence TCP/IP. Most web traffic uses the TCP protocol, including email and other protocols, such as HTTP, HTTPS, SMTP, POP3, IMAP, SSH, and FTP.

If a TCP hostname is requested (e.g. example.com), the request goes out to a DNS server and gets converted into an IP address.

Troubleshooting

  • Double check the TCP address, including the port, if set
  • If using a hostname, try running a DNS Lookup on your domain to see if there are any issues with your DNS servers.
  • If you are a paid member of MxToolbox, you can view the history and performance data of a monitor you’ve set up to pinpoint when this problem started occurring.
  • One of the best ways to get help if you are a MxToolbox paid member is to create a support ticket, and one of our staff will be happy to assist you.
