Error Message: “11004 unable to make TCP connection” when transmitting

CAUSE

This behavior can occur if any of the following are true:
  • There is no active internet connection.
  • The Central Site IP address is not configured properly in the program.
  • A firewall is preventing transmission.

RESOLUTION

Method 1 - Establish an Internet connection:

If there is no internet connection available, the program will be unable to transmit. Verify internet connectivity by opening a browser and connecting to a website that has not been connected to previously. Connecting to a recent website may not show if an internet connection is not working as modern web browsers store information from prior visits and can often display a revisited website even without an internet connection.

Once the internet connection has been reestablished, attempt another transmission.

Method 2 - Verify the configured Central Site server address is correct

  1. Log into the program as a user with Administrator rights.
  2. On the Work in Progress Summary (WIP) click Transmit on the top bar. The "Transmit To Central Site" window will open.
  3. On this page, click Setup. The "Central Site Communications Settings" window will open.
  4. Select the Advanced tab.



  5. In the IP Address box, type "answer.petzent.com".



  6. Click OK to save the change.
  7. Transmit to the Central Site.

Method 3 - Add an exception to the software or hardware firewall on the network:

Basic firewall information:

  • A firewall is a program that prevents a computer on a network from connecting to unknown sites.
  • There are two types of firewalls, software and hardware.
  • An example of a hardware firewall would be one that is run by a piece of equipment connected to the network, such as a network router or a cable modem. Many of these devices come preconfigured with a firewall that runs from at all times.
  • And example of a software firewall would be piece of software that runs on a computer, such as antivirus software or internet security suites. Many of these also enable a firewall by default.
  • An exception may need to be added for the IP address of the Central Site. Again, this address is:
