Please I need your help, before I was able to browse our website’s file manager without this error, but when I add a new user for purpose of test website, now the issue occur, when the admin tries to browse the file manager this error appear “unknown error” (please find the screenshot), I already deleted the user, but same issue, and the problem I don’t have access to our ubuntu server.
If you don’t have access to the server as root… it’ll be hard to debug and fix it. As you already modified the sshd_config file and it looks good, you could try to rebuild your user:
But why is it timing out? Do you have your SSH port open?
I don’t know how those credentials are managed by your hosting company so maybe… Anyway, if they provide a way to access your server via terminal from their control panel you could modify root credentials. The best you can do is to ask them about this.
I tried using Putty, I was able to proceed on the log in, but I tried to put the credentials, still access denied. Maybe I should communicate first to the support on this and ask for the access. Will get back to you if I have already access to our server.
