*Network is unreachable* when `ssh` on `crontab` `reboot`

On work Wi-Fi on my Debian 12 GNOME work laptop:

crontab:

@reboot autossh -NR 2224:localhost:22 benjamin@XXX.XXX.XXX.XXX > stdout.txt 2> stderr.txt 

Same with ssh.

stderr.txt:

ssh: connect to host XXX.XXX.XXX.XXX port 22: Network is unreachable

stdout.txt is empty.

ps aux | grep '[s]sh'

Output:
