Nightbot isn't working as it should on YouTube

[C.A]

Hi I need a little help. We have a few live chats running and yesterday Nightbot wasn’t working on any of them. Today it’s working but only in 1 of them. I can’t make him to post any commands or timers or delete anything on the other chats. What can I do? And can could be the reason?

Hiya. This looks related to this topic, which is still in investigation:

YouTube <> NightBot no response (for me). Was working fine yesterday!

All of a sudden NightBot does not seem to respond anymore for me (YouTube) Even a simple custom !hi command does not work! Same with any of the default commands… No luck NightBot does not seem down (seeing it active on other YouTubers channels). and my account is definitely not an inactive one! Any suggestions what it could be? Thank you.

Ahh yes. Nightbot stopped working on YouTube the other day for most of channels. He came back but, for me, he is not working on all the live chats. He is only responding the commands for 1 live chat… it never happened before though. Even if the other chats have about 40 viewers most of the time, he always responded to the commands and was posting the timers… until yesterday.
