Ssh malfunction

Hello everyone,

i recently got my secong bananapi, (my first one was working fine), but for some reason, the new one has a malfunction in ssh.

This malfunction consists of the following: I cant log into it from outside of my LAN. I installed the noip duc on it like i did on the first pi i have and on this one, it was working fine. but for some reason, i can only log into the pi via ssh when i use the network intern address. I even removed the passwords and used rsa keys instead, which works just fine network intern but for some reason not from the outside. (it does on my other pi and i did exactly every step on my new one like i did on the old one…)

so if anyone can help me, i’d be very very very grateful beacuse i’ve been trying to solve it for almost 3 weeks and by now i have literally no idea what else i should do

have a nice day, and thanks in advance

P.S.: the error mesage i get while trying to login is “Permission denied, please try again” while the same password and username works with the intern address just fine…

have you tried with others BananaPI image ?
