@fabriziotoniolo this is strange. Sorry about this trouble but I think we can figure it out.
Can you tell me which version of the agent you have? Right now the latest is 1.0.32.
I suggest you basically start over. To do that, rename your current .TRIGGERcmdData folder and close and open the TRIGGERcmd agent. It will re-prompt for a token then it will create a new computer. Delete your old computer record from your account after you confirm the commands are syncing.
After that, you can restore your commands by copying your commands.json from the renamed folder.
You'll probably want to make your new computer record your default computer too.
