no supported authentication methods available

[incognio]

I can not login to my server with ssh. When I enter my username (root) I see dialog: "no supported authentication methods available".

Last I remember was that I did some changes and restricts for users with shell access in WHM.

And I couldn't login to the server trough ssh
WHM was still opened, so I restart the server via WHM.
After that I can't access WHM, CPANEL, hosted domains on my server and I haven't shell access.

What I did?
Can this be fixed? Or I have to reinstall everything.
My server is colocated and I haven't direct access to it.

Does anybody can help me?

I think you should seek for your host provider to access through the server through console and check on the /etc/ssh/sshd_config file.

You can try using the SSH autofixer that is built into the WebHost Manager. You can call it using the following URL:

http://your_server_ip:2086/scripts2/...safesshrestart

Replace your_server_ip with the actual server IP address. This function will attempt to restart sshd with a very basic, default configuration, with sshd listening on port 22. If successful, this will allow you to log in and investigate and correct any problems in your sshd configuration (/etc/ssh/sshd_config).

If the autofixer does not help, you will need to contact your service provider for assistance, because either a remote console or physical access to the server will be required to fix the sshd problem.

Thank you for your help but I already decided to fix it by the hard way.
I'm back to inform you about what I did.

I contacted my data center and cPanel support.
Nobody couldn't help me.
So my decision was to reinstall the operation system.

Except 50 eur for reinstallation I didn't lost other because I was still testing cPanel on my server.
I hope never see this problem again.

From cPanel Support promised to do the new cPanel installation for me and I'm sure with your support everithing will be allright.

Thank you!
