Hit the nice red-orange power button on the top right of the sinusbot website perhaps.
I reviewed the output of the pasted log above. It claims that the bot is unable to connect to the server, but then says something about a missing configuration file at the end.
Is your server's minimum security level set to 8?
I've also attempted to join the server mentioned in the pasted log. If I myself have no connection issues, it may be that the bot'/ security level is too low, is banned from the server, or is severely broken somewhere.
Should you decide to reinstall your bot, please feel free to use the auto-setup script listed here:
