How to solve a problem with access to the control panel

With TrueConf, you can deploy a video conferencing system based on TrueConf Server Free which is extremely easy to set up: the installation process won’t take you more than 15 minutes!

When installation is complete, you can open the admin control panel in your browser. If the server was installed on Windows, the browser will automatically open the page with the address http://localhost/admin/. After installing the server on Linux, you can go to the control panel from any PC in the corporate network by using the local IP of the machine. Sign in with the user account created before to register the server and continue work.

If you cannot authorize in the control panel, try the following recommendations.

Unable to authorize as the administrator in the control panel

Problem description:

1. You are accessing the control panel page by using the external address.
2. Then, you type the login and password.
3. When you enter account information, the page is refreshed, and you are returned to the authorization window.

In this case, try to access the control panel by using the server domain address (FQDN). You specified this address when registering the server.

Checking the status of the TrueConf Web Manager

During the TrueConf Server installation, the following services are added to your system: TrueConf, TrueConf Database, TrueConf Web Manager. TrueConf Web Manager is responsible for accessing the control panel.

To check its status, run Task Manager and proceed to the Services tab.

Start it by clicking the Start button in the pop-up menu. If the issue persists, proceed to the next step.

Checking the control panel TCP port

When the server is installed, several services are added to the system, including TrueConf Web Manager. This service is responsible for providing access to the control panel.

On Windows

To check its status, run Task Manager and proceed to the Services tab.

Start it by clicking the Start button in the pop-up menu.

On Linux

All the commands should be run on behalf of the administrator or with the help of sudo.

Check the status of the service (known as daemon in Linux):

If the service is inactive (it has the Stopped status), run this command to launch it:

If the service is not started, go to the next step.

How to find out the port for accessing the control panel

During the server installation process, you need to specify the Web TCP Port (the port used for accessing the control panel). By default, it is set at 80 (or 8888); however, it could be changed later. So, one has to find out which port is now selected for accessing the server control panel.

Run any text editor as the administrator and open the file:

• on Windows [install-path]\httpconf\conf\listen.conf where [install-path] is the server installation path. C:\Program Files\TrueConf Server\ is used by default.
• on Linux distributions: /opt/trueconf/server/etc/webmanager/httpd.conf

Check the value of the Listen parameter. For example, the line Listen 80 means that TCP port 80 is used.

Checking the control panel TCP port

Check if the port is occupied at the moment.

On Windows

In the task manager, proceed to the Performance tab and select Open Resource Monitor. Unfold the Listening ports list on the Network tab.

If you use port 80 by default, it must be occupied by the tc_webmgr.exe file.

If the Web TCP port is occupied with a different process, you can change it manually without re-installing the server.

1. Go to the directory where the server is installed. By default, it is C:\Program Files\TrueConf Server\httpconf\conf\.
2. Run any text editor as administrator and open this file listen.conf. Change the port in the Listen parameter and save the changes.
3. Open the file \manager\etc\manager.toml as the administrator and specify the same port in the parameter:
   [web] connection = "<address>:<port>"

   1 2	[web] connection = "<address>:<port>"

   For example port 8888

   [web] connection = "10.10.100.2:8888"

   1 2	[web] connection = "10.10.100.2:8888"

4. Please reboot the computer on which TrueConf Server is installed.

On Linux

To check if the port is occupied, run this command on Linux

As a result, you will see the line with the list of PIDs or the IDs of processes that use this port:

Since you have previously made sure that trueconf-web is not running, this port is occupied by other services. In this case, you have to change the port:

1. Open this file as the administrator
   /opt/trueconf/server/etc/webmanager/httpd.conf

   1	/opt/trueconf/server/etc/webmanager/httpd.conf

2. Change the port number in the parameter Listen , for example Listen 8888. Next, save your changes.
3. Open the following file with any text editor:
   /opt/trueconf/server/etc/manager/manager.toml

   1	/opt/trueconf/server/etc/manager/manager.toml

4. Specify the same port in the parameter
   [web] connection = "<address>:<port>"

   1 2	[web] connection = "<address>:<port>"

   For example:

   [web] connection = "10.10.100.2:8888"

   1 2	[web] connection = "10.10.100.2:8888"

5. Restart the web server service:
   systemctl restart trueconf-web

   1	systemctl restart trueconf-web

In your browser, open the TrueConf Server control panel at http://localhost:<port>/admin/, where <port> is the port you have specified.
