(Data request failed with error: 'No network route' (205)

Hi all,
could someone tell me why I can’t control the device called “switch magazzino” even though the connection with the router “switch quado 1” is active? the connection with the coordinator is zero but with the router it is 35.
I report the complete error log:
z2m: Publish ‘set’ ‘state’ to ‘Switch magazzino’ failed: ‘Error: ZCL command 0xa4c138ea92f8304b/1 genOnOff.on({}, {“timeout”:10000,“disableResponse”:false,“disableRecovery”:false,“disableDefaultResponse”:false,“direction”:0,“reservedBits”:0,“writeUndiv”:false}) failed (Data request failed with error: ‘No network route’ (205))’

Not enough routers. That router itself does not have a connection with the coordinator.
