Hello, I'm trying to connect to a server using a private key. However, I get this error message and I don't know what it means.
It seems like the biggest thing I could have done wrong is make an improper private key file.
file. Would this error explain that?
Error:
```
CONNECT hostname
Exhausted available authentication methods H2.c: Problem getting public key from
k1.b@68947a4
```
EDIT. I made sure that the private key was named id_ed21559 and the directory also contained a public key with the file name id_ed21559.pub and now I get a different error message:
```
CONNECT hostname
Exhausted available authentication methods H2.c: Problem getting private key from
k1.b@2b6ccc9
```
The .pub file contains:
```
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIE9+2M9kJwAntOE6lnX6OgBmdfBHqrWY59HpXXCuwyr3 JuiceSSH
```
Any ideas or hints appreciated.
EDIT2: solved this by pasting in the "optional" key passphrase -- it appears that it is not optional, and andftp will not prompt for the passphrase.
