You should: Create network or provide correct one

Cause

  1. Incorrect value was specified for the --backnet parameter of the script.
  2. Container network was already converted to bridged mode.

Resolution

  1. --backnet parameter requires the name of the backnet bridged network created on the hardware node, not the name of the host-routed interface of the container. Please review the guide and configure bridged networks on the hardware node according to the guide http://download.automation.odin.com/poa/5.5/doc/index.htm?fileName=74135.htm

  2. In case when bridged mode is already configured for this VPS, use the following article to fix the issue:
