Ubuntu 14 server / Webmin / sftp not workking anymore
Yesterday, sftp was working fine, and today I can’t establish a connexion to my server through sftp.
It’s surprising because I didn’t change anything and I didn’t update any package.
I am using sftp (ftp through ssh) on port 22, and now I have the error message on my client (Fireftp of Firefox) which is
Can’t establish a connexion. Please try again later.
I don’t know which log file to check, there is nothing on /var/log/auth.log.
It’s like the port 22 is blocked and yet I didn’t modified anything.
Thank you for your help.
