NIghtbot is not responding to my commands in twitch

Nightbot is in my twitch viwers list but when I tried to use the commands (!commands). It doesn’t respond to me at all. Not only me but my followers also can’t use the commands. I also tried to part the channel and putting it back in my channel for 10 times already. I also but it as a moderator. And I check the logs that it havent been responding for 3 days already. I search everywhere for the solution and I cant figure out why. So please do help me T^T

This is my twitch:

If there are no updated logs then Nightbot is not in your channel. You might have luck trying to part with the !nightbot part command and rejoining him through the control panel.
