Why can't I connect to my Raspberry Pi via SSH?

Question

SSH

Finally I bought a flash card and decided to make a mini server out of Malinka for myself. I installed the terminal version of Raspbian Buster Lite, because the graphical component on the server is not needed, and I'm not going to connect via VNC.
It would seem that I did everything as indicated on the sites, using the raspi-config command, I went to the control panel, got to SSH, installed enaible, even updated, rebooted, tried to access Malinka via SSH via PuTTY on the PC, gives the following:

It's strange, I tried to connect through the Termius application on the iPad and everything worked, but only when the iPad and Malinka were connected to the same router, I had to connect the iPad to another Wi-Fi point and zero reaction to the connection.
I also managed to connect to "Malinka" through another laptop with Linux installed through the terminal, although I did not test it from another access point.
The question is what needs to be changed either in the settings or in the Raspberry files so that it can connect to it via SSH as easily as to a VPS, for example, from different access points.
Maybe it's in /etc/ssh/ssh_config or sshd_config files?
