No supported authentication methods available in FileZilla

Question

I'm using FileZilla to connect to my SFTP server. But when I'm trying to connect, it gives me this error

Error: Disconnected: No supported authentication methods available (server sent: publickey)

I have generated a private key with PuTTYgen and added it to FileZilla but this error still appears.

What does this error mean? And how can I solve it?

Solution 1

The error means that FileZilla tried all available authentication methods and have not succeeded. In your case, there was only public key authentication method available (a method that the client [FileZilla] and the server agreed on mutually).

As you claim that you have set up FileZilla correctly, chances are that you have not configured the public key on server-side.

For instructions see:

• https://winscp.net/eng/docs/guide_public_key or
• https://www.howtoforge.com/how-to-configure-ssh-keys-authentication-with-putty-and-linux-server-in-5-quick-steps and
• Disconnected: no supported authentication methods available

Though actually all the guides expect that you have a way to connect (e.g. password authentication). What does not seem to be the case. Possibly your server administrator/hosting provider has its own mechanism for setting up the public key authentication.

If you specify, what is your server like, you may get more specific answers.

I had similar issue error was Error: Disconnected: No supported authentication methods available (server sent: publickey)

Ans: Simply go to filezilla-Edit-settings-sftp-Add key file--add your ppk file-ok

connect again and issue resolved

Diff answer than 5 other answers here above (as of this moment)

I received this authentication error- No supported authentication methods available (server sent: publickey) repeatedly while connecting to my google cloud project and connecting thru FileZilla, even when I had spent hours checking my every step again and again by watching diff youtube videos and reading articles over Digital Ocean and similar.

But finally succeeded in a second, when I went into GCloud> Desired Project> Compute Engine> Metadata (in the left bar)> Metadata (in the main Pane)> and there I changed ' enable-oslogin' from 'True' to 'False'.

I had, sometime in my overzeal, had put in this key yesterday while doing something else.

I had the same problem and managed to solve the issue.

When using filezilla and sftp, it is important that you have full permissions for the folder where the ppk file is

Easiest way is to save the ppk file in the USER\your_user_name\Documents folder. You may need to set permissions manually for other locations.

This just happened to me, if it was working fine before updating FileZilla then just fix it by deleting your site from your site manager (CTRL + S) and recreating it.

Apparently that update will not take your old configuration files properly.

The OP explicitly says "I have generated a private key with PuTTYgen and added it to FileZilla", so your post does not answer the question.

This worked for me,

This didn't work for me. It never asks me for the password for some reason.
