Cannot access the Places or Cmap Cloud

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:

Code: Select all

Port	Mode   Protocol	Description of service

4447	Output	TCP	Connect to most CmapServers
443	Output	TCP	Connect for IHMC Public Cmaps(1), (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
4747	Input	UDP	Broadcast discovery of Places located on the LAN
4999	Output	TCP	CmapTools' WebSearch Server
5001	Output	TCP	WordNet Server
8001	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.
