The login attempt fails when using the identified key not the name default

[CookedMelon]

I'm not quite sure if this issue belongs to GUI or SSHFS itself. I've noticed that when I mount the machine using the SSH login key located at C:/User/.ssh/id_rsa, it mounts successfully. However, if I use a different file as my login key, such as id_rsa_linux, it fails to establish a connection (even though I can use id_rsa_linux to log in to SSH successfully and have correctly specified the key's path in the GUI).

success when I use "C:/Users/cc241/.ssh/id_rsa" to login

fail when I use "C:/Users/cc241/.ssh/id_rsa_linux" to login

You can see that I can login SSH with both key

Regarding the error messages, I ran the commands for both the failed login and the successful login, which were printed in the DEBUG OUTPUT. Here are the results:

Error report（Actually, regardless of whether I use the command that succeeded or failed in the GUI, it fails when I enter it in the command prompt (cmd), and I don't know why.）

Same problem for me.
It must be a sshfs-win-manage problem since in SiriKali I can specify my path to the key and it works fine.

[Edit]
I did some more testing and it seems as soon as you add a second entry to the connections it uses your specified path to e key file just fine, even if you delete the etries again.

I think I've the same issue:

I tried with no passphrase, with passphrase it is the same

I tried with key generated byopenssh and putty, it is the same...

However whith SFTP Drive it works.... so key and configuration are goods.

With Notepad++, please :

• change EOL to UNIX (LF)
• be sure to terminate by a newline
  
  

That has solved my problem.
