I do not know if it is the correct area, but I am going to explain what hapens with my system. I am using openhabian 2.4 on a raspberry pi 3 B+ model since first week of february, almost 2 months. Untill today I have no problem with it.
But today, when I tried to connect by SSH, I realised that I can not connect, and when I arrived at Home, I checked that I could not connect locally to. I am sure that I have not change the password.
The last I did with openhabian was to update. I do not know if someone could help me.
P.S: I am sorry for my English, it is rusty
