All of my SFTP connections are broken

Post by notorious.dds »

Hi All,

I've been using AndFTP for some time now. However, I've recently discovered that I can no longer connect to any of my SFTP servers. They used to work with AndFTP, but suddenly do not. I have no problem connecting to them via any other SFTP client... just AndFTP. I've tried a number of things including uninstalling the app and then reinstalling following by setting up connections from scratch. It made no difference.

The error I'm getting is:

"Exhausted available authentication methods c5.c: Problem getting public key from w2.a@*******"

The last 7 characters of the error (aka those coming after the '@' symbol) change depending on my attempt. The rest of the error stays the same.

All of my servers are configured with the following auth/encrypt methods and haven't changed for some time:
HostKey /etc/ssh/ssh_host_ed25519_key

kexalgorithms curve25519-sha256,curve25519-sha256@libssh.org,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256

hostkeyalgorithms ecdsa-sha2-nistp256-cert-v01@openssh.com,ecdsa-sha2-nistp384-cert-v01@openssh.com,ecdsa-sha2-nistp521-cert-v01@openssh.com,ssh-ed25519-cert-v01@openssh.com,rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,ssh-rsa-cert-v01@openssh.com,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519,rsa-sha2-512,rsa-sha2-256

macs umac-128-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com
Currently:
  • I'm using version 6.4 of AndFTP on a OnePlus 10t phone running Android 13.1, and
  • All of my connections within AndFTP have the "SSH provider" setting found in "Expert/specific FTP settings" set to "Secure (includes ED25519)"
I have 2 questions:
  • Does there exist a list of compatible connection methods for AndFTP with which I can use to tweak my server configs to become compatible with AndFTP?
  • Is there a way to see a more verbose error log for the AndFTP client?
Thanks!

You've upgraded SSH support in AndFTP 6.7. Could you try it?
