Remote side sent disconnect message type 2 (protocol error): "ssh connection closed by server" FATAL ERROR: Remote side

[hg363]

I have a batch file with the following command

plink.exe -ssh SWITCH-IP -l ACCOUNT -pw PASSWORD -v -batch

Plink switches

-l User
-pw Password
-v Verbose – Show all
- Batch Login automatically
-ssh Protocol to be used


C:\temp\1>plink.exe -ssh SWITCH-IP -l admin -pw PASSWORD -v -batch

When the batch script is executed, the following output is generated.
