plink FATAL ERROR: Network error: Connection refused

I'm trying to capture traffic and dump it into wireshark for analsysis. But somehow i'm unable to connect to the edgemax router, it gives me the error message: FATAL ERROR: Network error: Connection refused

I've tried:

plink ubnt@192.168.1.1 -telnet -P 23

plink ubnt@192.168.1.1 -telnet

plink ubnt@192.168.1.1 -ssh 

plink ubnt@192.168.1.1 -ssh -P 22

plink -ssh -l ubnt -pw ubnt 192.168.1.1

Configuration:

}
ssh {
port 22
protocol-version all
}
telnet {
port 23
}

I'm able to SSH from Putty with the same IP, username, password but it fails for plink. Did anyone run into this error?
