Tasmota RF Bridge stuck

Sorry if I had to post this question under another category, not sure which one.
I have a Sonoff RF Bridge with tasmote 6.7.1 running quite well. I use both learned codes and codes sent with Rfraw command.

Today it failed to send any commands. I see in tasmota console it attempts to send commands but nothing happens: RF devices do not react.

21:14:10 MQT: sonoff_rfb/stat/RESULT = {"RfKey3":"Learned sent"}

trying to send the command from the console… no dice. soft reboot does not solve this behavior. The only way to fix it is the cold reboot.

My questions is - how can i monitor this situation from hassio ? the tasmota did not have any error in its log. I do not know what happened. I think if I schedule a soft reboot from hassio it will not help. Have you ever faced such case?
