Cannot connect RPI4 with wifi

[RPI_Beginner]

Hi!

I bought a PRI 4 a few days ago. I followed every step of this tutorial https://www.youtube.com/watch?v=BO1KYIPIn9Y and flashed the system on a SD cart. My problem: I cannot connect the RPI with the wifi (i cant see the IP).

My Wifi config:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
ssid="ccc"
psk="ccc"
}

The LEDs shine red and green (blinking. I use a Mac.

Can someone help me?

Thank you!!

Is your SSID hidden?
What do you get from iwlist scan wlan0? Does your SSID show up in that scan output?

Thank you for your reply. No my SSID is not hidden. I got this:

You have to run that iwlist command on your Raspberry. I care not a jot about whether your Mac has any WiFi connection or not.

Ahh ok i misunderstand you...but how can i run it on Raspberry?
Sorry im a absolute beginner

Plug in a TV, keyboard and mouse. Boot up the RPi. Open an LXTerminal window and try the command.

Wire your RPi to your home router, create a file /boot/ssh or /boot/ssh.txt, boot up and you can connect to your RPi with an ssh session from your Mac. Use that to determine what's wrong with your RPi wifi settings. Since you have an Apple Mac you may be able to use ssh pi@raspberrypi.local to find the system on your network with Avahi/Bonjour (Bonjour was invented by Apple).

Or use RealVNC to get screen mirroring running across that wired connection and do the LXTerminal stuff.

ok got it. Thank you!

A new problem occurred

after writing ssh pi@192.168.0.17

the terminal says:
ssh: connect to host 192.168.0.17 port 22: Connection refused

I add a empty ssh on the SD cart...but nothing happens.

Do you know what i can do?
