Hi,
Can you access CLI? I suppose so as you have posted the running config.
if so then in privileged mode( #) issue the following command: debug ppp authentication
then try to connect again and you'll see debug messages on the screen, copy paste on this forum
Regards.

Sorry guys

not rebooting but you can enter the debug command and then try this:
int dial0
no encap ppp
encap ppp

Run the debug command and then ran the no encap ppp and encap ppp command.
Still nothing on screen, doesn't look like its even attempting to authenticate

Hi,
are you connected with console cable or by telnet?

Problem is now fixed
I setup the ATM0.1 point-to-point interface DOH!
