This document describes the reasons why your browser might suddenly no longer work with the TelePresence Server.
Why does the browser no longer work with a TelePresence Server?
This may happen if the HTTP/HTTPS service is disabled on the TelePresence Server. In order to enable the HTTP or HTTPS services, you must use the serial console because you cannot reach it via the web interface:
Connect to the TelePresence Server via the serial console.
Enter the service show command in order to determine which services are enabled.
If the HTTP service is not enabled, enter service 0 http enable in order to enable HTTP on Port A. (Similarly for HTTPS, enter service 0 https enable.)
Restart the TelePresence Server.
Once you have HTTP/S connectivity to the TelePresence Server, you can use the web interface in order to modify the active services and ports:
Log into the TelePresence Server and go to Network > Services.
Check/uncheck the boxes next to the service names and edit the port numbers if necessary.
