I have tried to add kex to config files but I am still unable to get this to work. It was working at one point but I did not back it up or write instructions because I thought I would never have to touch it again, until I did 😊
Need help establishing the recipe again. Any help would be appreciated. $ cygcheck -c Cygwin Cygwin Package Information Package Version Status cygwin 3.1.7-1 OK SSH Results: debug1: Local version string SSH-2.0-OpenSSH_8.3 debug1: Remote protocol version 2.0, remote software version LiteSSH debug1: no match: LiteSSH … … debug1: kex: algorithm: (no match) Unable to negotiate with 10.0.3.6 port 22: no matching key exchange method found.
