In some environments access to the internet is only granted by going through a proxy server. This will obviously also affect the Cloud Bridge to Signl4. In order to add the Proxy to your configurations you will have to alter 2 files:
C:\Program Files\Enterprise Alert\WebSites\EAPortal\web.config
C:\Program Files\Enterprise Alert\ChannelHost\ChannelHost.exe.config
And add the system.net section below right before the closing tag of the configuration </configuration>
<system.net>
<defaultProxy>
<proxy proxyaddress="<Your_Proxy_Server>"
bypassonlocal="True"
/>
</defaultProxy>
</system.net>
The process should be as followed:
1. stop the ChannelHost Module
2. make backup of the web.config and channelhost.exe.config
3. add the above section
4. save both files
5. start the ChannelHost Module and run an IISreset
