I have a RPi 3 Model B+ and I used it as WiFi bridge for a device which has only ethernet port. After the initial setup it worked and then after one reboot the SSH stopped working.
It’s connected to WiFi, I can see it online on my router. I can ping it from my PC. I can access folder which I shared over the local network from it. The only thing I can’t do is remote into it with RDP or SSH with Putty.
SSH should be running:

    sudo systemctl status ssh
    ssh.service - OpenBSD Secure Shell server
     Loaded: loaded (/lib/systemd/system/ssh.service; enabled; preset: enabled)
     Active: active (running) since Tue 2024-07-30 19:28:41 CEST; 2min 15s ago
       Docs: man:sshd(8)
             man:sshd_config(5)
    Process: 806 ExecStartPre=/usr/sbin/sshd -t (code=exited, status=0/SUCCESS)
   Main PID: 822 (sshd)
      Tasks: 1 (limit: 1557)

     CGroup: /system.slice/ssh.service
             └─822 "sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups"

Why is it not working?
