RPI 4b headless install can't ssh connect

[Ganimede]

Hello,

I'm trying to install Arch-ARM on my RPI 4b and followed this [url=https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4]installation guide[/url].

I followed all steps successfully up to the ssh connection. But connecting via ssh just results in this.
[code]ssh alarm@192.168.178.XX
ssh: connect to host pi port 22: No route to host[/code]

In my attempt to find a solution I found [url=https://archlinuxarm.org/forum/viewtopic.php?f=9&t=15486]this topic[/url] and I attempted to change the enty for dtoverlay=vc4-kms-v3d in /boot/config.txt which changed the result to this.

[code]ssh alarm@192.168.178.XX
kex_exchange_identification: read: Connection reset by peer
Connection reset by 2a02:8108:240:2bc:b9eb:640b:e96e:3007 port 22
[/code]

I'm aware that both of those responses are very generic, but I have no idea how to approach this further as I can't even connect to the Installation.

[b]Exclusion of possible failue points:[/b]
I use openSSH and I'm able to connect to the RPI with RasperianOS as well as my notebook running Manjaro. (ssh client is running on Endeavor OS)

uSD-card was running with Rasperian OS right up to the point of my installation attempt on the same device. Another card with Rasperian is still functional. So I have no reason to believe the card or the device is at fault.

Device is connected to the router via cable and ssh login is possible with Rasperian OS.

Seems like the [u]BBCode[/u] is broken.

I got another confusion regarding plattform of the RPI 4b. Here in the forum it is in the ARMv6 section, the install sources use the ARMv7 tag and https://archlinuxarm.org under platform lists RPI 4 under ARMv8.

The image is setup to use DHCP. Connect via a cable and look at your router. Is it serving up an IP to the Pi? Are you sure it's the one your trying to connect to? RPi4B can use armv7h or aarch64. Recommend you run aarch64.
