Error from JS Client but works from CLI and GUI Apps

Error message: connect: getConnection: All configured authentication methods failed

Config defined

• host
• username
• privateKey
• port

Maybe these fix this bug:

• Added rsa-sha-xxx key sig support mscdex/ssh2#1200

Maybe related issue:

• publickey auth fails in ssh2, but works from command line mscdex/ssh2#989
• QUESTION: Need help connecting via SSH tunnel beekeeper-studio/beekeeper-studio#1240

This error typically occurs because the remote sftp server you are trying to connect to does not support any of the default key exchange or cipher algorithms being used. There are a number of additional key exchange algorithms and ciphers which can be enabled using the algorithms property of the connect method. See the ssh2 documentation for details. One method I find useful is to use openssh' CLI sftp program, add -vvv to turn up debugging information and try connecting to the remote server, The debug information will show you what key exchange algorithm is being used and which cipher ends up being agreed upon. Once you have this information, you just need to find out what the ssh2 program calls those key exchange algorithms and/or ciphers and set them in the algorithms propety in the connect call.

I sure it will fix this bug mscdex/ssh2#1200

For now, on server changing as mentioned here works, but without this Cyberduck macOS and sftp cli works fine

Well as this is an ssh2 issue, there is nothing I can do as this module uses ssh2. So, until ssh2 is updated, your only option if you want to use this library is to use a different key signing algorithm, such as ssh-ed25519 (this is what I do) or find a different library.
