Handshake failed: signature verification failed

[DehanLUO]

zsh, MacOS Termianl
ssh [email protected] -p 2122 works with the following config at ~/.ssh/config

#device
Host 172.16.176.181
  HostName 172.16.176.181
  KexAlgorithms +diffie-hellman-group1-sha1
  HostKeyAlgorithms +ssh-dss

However, with the following config in Tabby(1.0.167)

profiles:
  - type: ssh
    name: 172.16.176.181
    icon: fas fa-desktop
    options:
      host: 172.16.176.181
      port: 2122
      user: admin
      algorithms:
        hmac: []
        kex:

        serverHostKey:
          - ssh-dss
      privateKeys: []
      forwardedPorts: []
      scripts: []

I always get following errors when I get access to my device

This likely due to no algorithms being selected for message authentication and encryption - try with a clean profile created from the UI + the diffie-hellman-group1-sha1 kex.

Thanks for your help.

I reinstalled the tabby and cleared the cache

brew reinstall tabby
rm -rf /System/Volumes/Data/Users/dehan/Library/Application Support/tabby/

I added diffie-hellman-group1-sha and ssh-dss from the UI.
However, the same error occurs again.

It happens the same to me.
This configuration works perfectly in the ssh config file.

But applying it on Tabby, it doesn't work.

Please, we need a solution. Tabby is what we have always wanted but with this problem we cannot use 90% of our devices.
