Ah. Order matters. 

winscp> open sftp://lewiske:abc@10.128.90.20:3389/ -rawsettings -hostkey="ecdsa-sha2-nistp256 256 KmlymX4521gtpAaOhSrz4UY9CAEO+JNiAFTCQ/XqbUN=" Tunnel=1 TunnelHostName="172.26.170.21" TunnelUserName="kris.ctr.lewis" TunnelPasswordPlain="xxx"

Too many parameters for command 'open'.

But re-arrange the order, and get...

Got it. I must have missed this in the docs... Oops.

I do not. Even with your old WinSCP 5.13.7, your command with -rawsettings added, works as expected.

Problem is no longer an issue. I moved the open statement out of the script. it's now part of the DOS Batch line that starts the process - WinSCP.exe "servername" /log=log /script=script
and the script starts with the first non-"open" command

Re: Connection OPEN works in GUI, not on console/script

Your updated open command is missing the -rawsettings switch: 
open sftp://.../ -hostkey="..." -rawsettings Tunnel=...

Connection OPEN works in GUI, not on console/script

Windows 10/1909. WinSCP ver 5.13.7
I have a server that I connect to via a tunnel regularly. Here is the open command as generated inside WinSCP for scripting: 
open sftp://lewiske:zxcv%2F456@10.128.90.20:3389/ -rawsettings Tunnel=1 TunnelHostName="172.26.170.21" TunnelUserName="kris.ctr.lewis" TunnelPasswordPlain="A10THlt-!)"

(passwords altered from reality, but format left intact)
Using commander GUI, connection opens and works properly, no issues.
When I attempt to use that open command in /console, I get this:

Opening tunnel...
Searching for host...
Connecting to host...
Authenticating...
Expected host key was not configured, use -hostkey switch.
Host key fingerprint is ecdsa-sha2-nistp256 256 KmlymX4521gtpAaOhSrz4UY9CAEO+JNiAFTCQ/XqbUN=.
Authentication failed.

(fingerprint slightly altered)
when I alter the open command to include the hostkey as instructed, using this open line: 
open sftp://lewiske:xxx@10.128.90.20:3389/ -hostkey="ecdsa-sha2-nistp256 256 KmlymX4521gtpAaOhSrz4UY9CAEO+JNiAFTCQ/XqbUN=" Tunnel=1 TunnelHostName="172.26.170.21" TunnelUserName="kris.ctr.lewis" TunnelPasswordPlain="xxx"

I get this:

Too many parameters for command 'open'.

Help?
Log attached (with some added data) though it does not seem useful. It gave no indication why the script failed - I found out in /console

(this server, the reasons for my connecting to it, and the data to be transferred are all Safety-of-Flight. I'm an Air Traffic Systems Field Engineer, the system is FAA). I can do what I need to do in GUI, but running scripts on the remote host in GUI mode is annoying - I shift to Mobaterm for that. I'd rather script the whole process.)
