based on: PowerShell/Win32-OpenSSH#1185 added full path and removed ' around websocat comman to get:

ssh -o "ProxyCommand=C:\Users\golem.cargo\bin\websocat.exe asyncstdio: ws://127.0.0.1:7465/net-api/v1/net/078025b62521435782b12a208376141c/tcp/192.168.0.4/22 --binary -H=Authorization:"Bearer 5c3f6bb221954498ba664ad41b85be5d "" root@b020e898fcb7438a9cf5eb3830409039
websocat: Unknown address or overlay type of asyncstdio:

suggested solution: replace websocat with a local socket proxy in yapapi?

[jalas167]

based on: https://github.com/vi/websocat/blob/master/doc.md

asyncstdio:
Internal name for --dump-spec: AsyncStdio

[A] Set stdin and stdout to nonblocking mode, then use it as a communication counterpart. UNIX-only. May cause problems with programs running at the same terminal. This specifier backs the --async-stdio CLI option.

Maybe we should not use that option (AsyncStdio:) during tests on windows?

when tried:

ssh -o "ProxyCommand=C:\Users\golem.cargo\bin\websocat.exe ws://127.0.0.1:7465/net-api/v1/net/078025b62521435782b12a208376141c/tcp/192.168.0.4/22 --binary -H=Authorization:"Bearer 5c3f6bb221954498ba664ad41b85be5d "" root@b020e898fcb7438a9cf5eb3830409039

output is (golem example was not running):

websocat: WebSocketError: I/O failure
websocat: error running
kex_exchange_identification: Connection closed by remote host

[shadeofblue]

we will resolve it by including a generic socket proxy in yapapi itself
