PuTTY will not connect

[LennyG]

My new Lenovo laptop with Windows11 home will not connect to a remote address using PuTTY. My main PC on the same home network works fine. On the laptop, I can ping the remote address, and can do a tracert to the remote address, and also I can use OpenSSH from the command line ( ssh xxx.xxx.xxx.xxx ) successfully. I even took the laptop to a WiFi hotspot, and got the same results. PuTTY will connect to local IP’s fine. I’m stumped, and need some hints on how to debug this. PS: WinSCP will not connect either.

That's strange - has the app been blocked by the firewall (perhaps mis-identified as a threat)? Do you have any other security software on the system other than Windows Defender?

Do you get any connection auth errors with PuTTY, or is it just a timeout? I'm using PuTTY on Windows 11 without a problem.

Same problem.
Have you found a solution?
