If in the Viewer you can see the message “Attention! No access to the Central Server. In order to restore the access, contact your Kickidler software package system administrator or use the following instructions”, follow the following steps in order to perform an independent access restoration:

1. Check to see if the Central Server is accessible from the computer, on which the Viewer is installed.

How to understand that there is no access:

Find the port (by default for Windows: 7906 and for Linux: 1025) in the node.ini file and run the telnet command in the command prompt.

Attention! Before using the telnet command, make sure that it is enabled.

Windows: telnet %ip address of the Central Server% 7906
Linux: telnet %ip address of the Central Server% 1025
Example: telnet 192.168.11.11 7906

Solution: if an error occurs, there is no access and you need to configure the mixed networks. Read more here.

2. Check to see if the firewall is blocking the operation of the Viewer and Central Server.

How to understand that it is blocking:

Open the command prompt and run the following commands:

telnet my.kickidler.com 40401
telnet %ip-Central Server Address% 8123 /8123 — port of the web-based interface of the default Central Server, if another port is specified in the node.ini file in the [http] block, it is necessary to first run the telnet command for that port

Solution:

It is necessary to perform the following for correct operation of the Kickidler software package:

allow outgoing connections for the Viewer and Central Server on my.kickidler.com to the TCP ports 40401 and 7905,
allow incoming connections to the TCP ports that are registered in the node.ini file (by default for Windows: 7906 and for Linux: 1025) and the web-based interface port of the Central Server (8123 by default or the port that is registered in the node.ini file in the [http] block).

3. Check to see if the Central Server is running.

How to understand that the Central Server is not operating:

go to your Personal account, open the section “Licenses”, and find your Central Server;
if the date and time are specified in the column “Recent connection” in the license table, these are the date and time when the Central Server last operated.

Possible Causes of Nonoperability:

the disc runs out of free space.

Solution:

Open the Central Server logs, which are located here by default:

Windows: C:\Program Files\KickidlerNode\log

Linux: /opt/KickidlerNode/log/

and check to see if there are any records in the log:

ERROR std exception during log video frame: ERROR:  could not extend file "base/16385/3710192.227": No space left on device
HINT:  Check free disk space.

If there are such records in the log, you need to clear some space in the database.

The Server service has not been started (nns for Windows, kickidlernode for Linux).

Solution:

If it has not been started, it is necessary to start it. If it has been started, restart it.

The database cannot be launched

Solution:

Open the Central Server logs and check the log records:

QPSQL: Unable to connect
2016-10-20 14:07:40.142 2424 ERROR database connection failed: could not connect to server: Connection refused (0x0000274D/10061)

If there are such records, check to see if the PostgreSQL processes are running and if they relate to the Kickidler software package Server component. If this is the case, complete all the PostgreSQL processes, associated with the Kickidler Server, and restart the Server service (nns for Windows, kickidlernode for Linux).

The directory, into which the Server has been installed, should not be used for the database

Solution:

Open the Central Server logs and check the log records:

2016-11-07 14:24:06.392 7696 FATAL unable to initialize data directory for internal
postgresql instance

If there are such records, reinstall the Server into the directory full path to which uses the Roman alphabet only.

Attention! If all of the mentioned above has not helped to solve the problem, contact the Kickidler Technical Support.
