I have a RN102, ReadynasOS 6.4.0

For some unknown reason my SSH was lost.

I followed the suggested link, the "backup" of the original sshd_config file seems to have some effect, but it is not enough.

TO actually fix it I have opended the zip file, edited the ssd_config file within the zip and REMOVED all kind of authetications (publickey, password, pam).

By doing so I was able to login and fix everything.

My SSH was inforcing Google 2FA, so this might have created issues with PAM
