Problem Resolving

Missing License​

  • Check if the license file is installed (HumanOS.lic).
  • A new license is needed to install the product on new hardware.
  • The license must match to your installed edition. Check the edition!

No Connection to Services like OPC-UA Server​

Most likely are missing firewall rules. Typically, when starting the HumanOS® Iot Gateway a window pops up asking to grant access over the network.

  • Run the HumanOS® IoT Gateway as console app first and grant the access, before starting it as a windows service.

Add both, inbound and outbound rules. Grant access to the ports.

No Connection to Device​

There are many reasons why a connection to a hardware or software system fails. For detailed information, read the device specific configuration manual. Following errors are the most common for ethernet devices:

  • Firewall restrictions
    • Firewall settings of the IPC
    • Firewall settings and routing restrictions when communication between different subnets

use ping and telnet <address> <port> to check if the device is available.

  • DHCP changes address of the device dynamically
    Disable DHCP and configure static IP for device
    or use the domain name as address.
  • Peer-to-peer.
    Older devices do not automatically recover peer-to-peer networking. Use a dedicated ethernet cable.

UnauthorizedAccessException​

The UnauthorizedAccessException appears if the program tries to read/write data within a directory and the user has to rights to read/write.

Typically, this exception is thrown when accessing the persistence data repository in C:\ProgramData\CyberTech\HumanOS.IoT.Gateway. Make sure the access rights are set to all users:

NodeSpace Initialization errors while Start-up​

An initialization error while starting up the node space might occur if an error in the persistence database happened. Typically, this error comes together with serialization or deserialization exceptions loading the node space.

This error can be resolved with the startup argument -cleanRepository.

  1. Backup the directory $ProgramData$\CyberTech\HumanOS.IoT.Gateway\
  2. Open the console window and navigate to the installation directory.
  3. Start HumanOS.Server.ConsoleHost.exe with
  • -cleanRepository=nodes : to clean only the current node space
  • -cleanRepository=all : to clean the complete repository (node space and history)

Running out of memory​

HumanOS® IoT Gateway collects all data according to the device specifications. The data is kept in the history repository.

If sample rates are very low (high frequency) lots of data might be collected. This could lead that the system runs out free disk memory space.

Short term resolution:

  1. Backup the directory $ProgramData$\CyberTech\HumanOS.IoT.Gateway\ to an external drive
  2. Make sure external MES or remote services get all needed history data before you continue.
  3. Open the console window and navigate to the installation directory.
  4. Start HumanOS.IoT.Gateway.exe with -cleanRepository=history to clean only the current history repository.
  5. Also check the log file size and the corresponding settings in the config-files.
    Use circular trace listeners for logging information.
