Make sure you are connected to the internet before you run CmapTools. If a list of Places (CmapServers) is not displayed when you click on the "Shared Cmaps in Places" button of your Views window, it could be because your machine is behind a firewall or using a proxy server to access the Internet. If you have a firewall on your computer, or your access to Internet is through a firewall, the firewall must be configured to allow requests through specific ports and protocols to go through.

You may need to contact your systems administrator if the firewall is part of the local area network your computer is attached to. The specific ports that need to be opened are:

Port
Number Mode Protocol(s) and description of Service

4447 Output TCP Connect to most CmapServers
443 Output TCP Connect for IHMC Public Cmaps (1), IHMC Public Cmaps (2) & (3), IHMC Cmappers
80 Output TCP Connect for IHMC Cmap Cloud
4747 Output TCP, UDP Connect to the Directory of Places to get the list of CmapServers (places)
4747 Input UDP Broadcast discovery of Places located on the LAN
4999 Output TCP CmapTools' WebSearch Server
5001 Output TCP WordNet Server
8001/80/443 Output TCP Web server of the CmapServer (Place)
31099 Output TCP Communication with the Index Server. Used by the CmapTools' Search.

If access to the Internet is through a proxy server, you need to configure the proxy settings by going to the "Preferences" menu entry (Edit/Preferences in the Views window) and selecting the "Proxy Configuration" tab.
