Domoticz

Suddenly all my virtual switches, linked via idx to all my tasmota devices on ESP8266 wemos d1 r2 platform are not working. The domoticz interface shows me only the state of each switch, but I cannot send commands via domoticz dashboard, but only via Tasmota interface.
This situation suddenly without any modification done in the firmware, neither on the Raspberry, nor in any of the 7 Wemos.

I need suggestions to fix my problem.

Tanks in advance
