Noticed the same on a TwoTrees Bluer printer with Marlin 2.1.1 Sometimes this happens directly after starting the printing process via OctoPrint. Printing process is not affected.

Hi @Salvora, would you mind posting your custom script to turn on / off port forwarding or a link to it?

Hi, I can confirm that on/off is working fine but the switch state itself is always "turned off".
