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

PUTTY may be using different port numbers so it will fail.
