Update: it could be that my smartphone was changing the first letter of the PW to a capital letter and I cannot see it on the screen, don’t know why. I now tried with my Samsung tablet and it worked. Thanks for opening my eyes 🙂 Take care guys.
Thanks for the answer 🙂 Yes password authentication. I am pretty sure, user and password are the same, Unless I am dreaming as I did the first setup months ago. As for the user login no unicode characters, all letters are “basic” alphabet. I even tried without entering any password at all, no change. Yes, it worked before. I tried to create another connection, no success… can you explain what you mean with “Verify also if you can connect from other host to the same server, maybe problem is on server side.”? Sorry, what should I do? By the way, sorry I did not really specify before, I want to control my xubuntu 18.04 pc via my huawei p30 pro.
