Issue Description

Some sites in our company, we have a plan for the upgration, after we upgraded the sites, we found that we can`t get the conference list in the touch pad.

Alarm Information

disconnection between terminal and host

Handling Process

As for the issue of conference list, the normal procedure is that terminal will get the conference list from the remote, if we can`t find the conference list in the touch pad, we need to check whether the conference list exits in the terminal.
This case is that we can find the conference list in the terminal, but we can refresh the conference list in the host/pad.
1. We know the we get the conference list via http connection between host and terminal, so first of all we need to check the connection between terminal and host, we know it means disconnection between host and terminal as following picture.

2. Diagnose this case according trouble shooting, we find in the host the name of http is empty. Because recently we have a upgration in our company, so maybe it`s caused by a high range between different version.

3. We suggest please do it as follows.
a. The 4th flip please make it down

b. Then reboot the host(plug the power out then plug in)
c. Make the 4th flip back to normal.

Root Cause

as follows


After we restore the user and password into normal, the case can be closed.We suggest be familiar with normal way to diagnose issue
