do you use RADIUS authentication server? what does it say in log?
activate additional debaug "ppp authen" "ppp negotia" "aaa authent"
but your error is quite obvious - you have username/password problems. check if you don't have any "space" characters in password or somwthing like this.

Hi,
Thank you for your response.
Yes, the problem is solved by the ISP since we upgraded the line from 2 Mbps to 4 Mbps (new line), it needs a reset by the ISP since it logged the old physical interface ID (2 Mbps).
Thanks again
