Ignition disconnected every 30 seconds

[mariusz-zapala]

Hi

I am running Nodered and Ingnition inside docker containers.
I have added "Ignition Tag Read ws" node and it is working, but status says "Ignition disconnected" every 30 seconds, after 3 seconds it becomes "value received" again. When I change variable value in Ignition every 20 seconds, in Nodered it doesn't disconnect.
It seems to be disconnecting if there is inactivity for 30 seconds.

Regards,
Mariusz

I fixed this issue in 1.5.18. This version does require Ignition 8.1.49+. I will be releasing an Ignition 8.3 version shortly.
