# Known Bugs List

  • Unable to create the Isolated Dryer Control Network (IDCN) when there is no input pressure.

    Solution: update FW to the version 3.3.2 or higher.

# DHCP server in the DCN with Enapter Cloud Connection


The issue is very rare and will be fixed in future FW releases.

If the DCN with Enapter Cloud Connection is used it is possible that DHCP (opens new window) server inside the DCN may assign IP address to a device connecting to the same WiFi AP to which devices from the DCN are connected.


  • Delete the DCN from the Enapter Mobile App and create it one more time.

  • If it is possible try to separate the DCN from your main network environment by connecting the DCN to another WiFi AP, no need to separate one DCN from another.
