Fibaro roller shutter 4 stopped working

hi - i installed a roller shutter 4.

installed. worked. since today not reachable. any idea ? all other roller shutter 2 are working.

Check the routes on Homey Developer Tools or share the screen.

The roller shutter has current? Does it show a warning in Homey? Is the zwave mesh correct?

there is no screen to share. it shows as if ok. say 1000ms timeout

no warning. only time out 1000ms. it worked before.
