There are a number of suggestions that will help identify the issue.

Also, ensure you enable debugging mode (ideally in both Joomla and Moodle) to find more details of the error message.

Also, I note you had a similar problem before

The steps to solve this are the same since you have the same error message. So, I would ask you what did you do last time to resolve this? Maybe it is the same problem.

Thanks for the help. I redo the token and it works.
