I bought Raspberry PI 4 and I need to connect to it via SSH because I do not have micro HDMI yet. I'm trying to establish the SSH connection, but PuTTY returns "Connection refused" error, but the IP is correct (The ping command on that IP works and in router administrations, there is a column with raspberrypi and IP to that raspberry). On SD card I have the Raspbian 4.19 burned using etcher, so the system should be booted properly.
You need to enable SSH on Raspberry.
Interfacing Options and navigate to and select
SSH and choose
If you don't have direct access to the Raspberry with a monitor and a keyboard place a file named exactly
ssh on the FAT partition of the SD card. This will activate the ssh server at the next boot.
You can find all the detailed instructions on Raspberry PI official documentation
