Login as: Debian -> Server unexpectedly closed network connection.

Hi!

I’m starting to learn how to use the beaglebone now and I’m a completely newbie in the area,

I’m trying to login for the first time as “debian” on my Windows using PuTTY, but everytime I try to do it, the system doesn’t let me input the password and the message “Fatal error: Server unexpectedly closed network connection” appears after some moments.

What could it be and how can I fix it?

Thanks

putty should have a verbose/debug option enable it, it should give
some hints on what's going on..

Regards,
