I cannot connect to my raspberry pi through ssh anymore...
Everything was working since the beginning: I removed the possibility to connect with a password, and I was connecting to my rpi using ssh and my ssh key for weeks.
But yesterday I installed node.js and I restarted my rpi, and now I am getting a "Permission denied (publickey)" when I try to ssh it.
What should I do to fix this issue? any advice? I can still plug a screen and a keyboard and log into it, and everything I checked (sshd config, ...) didn't changed...
Thank you for your help!
