How to access Raspberrypi via SSH after running a .py file at startup using systemd?

Question

I've set a .py file to run at startup of my Raspberry according to this guide : https://www.dexterindustries.com/howto/run-a-program-on-your-raspberry-pi-at-startup/

Method 4: Systemd

I did exactly as the tutorial, and the file does play at startup as expected. However, since that moment i've been unable to access the Raspberry via SSH or VNC, I ping to the Raspberry Address and I got positive response, but when I try to connect via SSH I get

"ssh: connect to host 192.168.1.250 port 22: Connection refused"

Since i'm working headless i'm unable to check what's wrong.

Any advice? thanks in advance!

Answer 1

Take the SD card out of the Raspberry Pi and put it in another computer. Create a file called ssh in the boot filesystem. Use touch ssh to create the file.

Put SD card back in Raspberry Pi and reboot. You will be able to ssh into it, then use sudo raspi-config to enable ssh permanently.
