Node Red rebooting Velux Nodes

Node Red keeps rebooting every 30 seconds when using the Velux KLF200 Nodes.

It says that it can not make connection /login and that the KLF200 gateway needs a reboot.
But thats not working, rebooting the KLF200 doesn’t make a change.

Does anybody have the same problem or knows a solution?

Thank,

Mischa
