"Nightbot can't recognize my user (OizoGG) – can't edit commands or add myself as manager

Nightbot

Nightbot is not recognizing me correctly. I can log in, and the bot is a mod and responds to commands like !lelo , but I cannot use !editcom or !addcom in chat – nothing happens.

This sounds like Nightbot is working normally, but that you have the !commands default command disabled in chat. You can edit default command configuration at https://nightbot.tv/commands/default

HTTPError Status Code: 400, Message: user not found

You cannot add yourself as a manager, so that would be why you get a 404 when doing that.

Can you please reset or re-sync my account in your backend?

This is not something we are able to do. Users must do this themselves: https://community.nightdev.com/t/nightbot-troubleshooting/24239
