Sam connect error: Timed out while waiting for handshake

Hi,
I have troubles connecting to my raspberry pi. I could not find it using

sam devices

but as I read here that shouldn’t be an issue. So I tried

sam connect 192.168.x.x

but this resulted in an Error:
× Error connecting to 192.168.x.x: Timed out while waiting for handshake

I can connect to the Raspberry via putty without issues (I’m using Windows 10).
Since I read about wrong ssh keys I tried to delete the ssh settings on my Raspberry:

sudo rm /etc/ssh/ssh_host_*

But I still have the same issue when trying to connect. I have tried both running command promt as local user as well as admin.

Can you help me?
Thanks and best regards!
