Okay. Your laptop can’t ping or SSH into the server. First, figure out if the problem is one-way. Can the server ping the laptop, or is it just dead in both directions?
You mentioned all other devices communicate normally—do they all fail to reach the laptop, or is the issue isolated to the laptop and server pair?
Physically check the server and confirm both IP addresses to ensure you’re not chasing the wrong info. Once you’ve got the correct IPs, ping the laptop from the server’s side. If the server can’t reach it either, you know this isn’t just a laptop-to-server problem.
Also, did you set up a firewall on the laptop? That’s worth looking into. And yes, it’s annoying, but try the simple stuff: disconnect and reconnect your laptop’s Wi-Fi, reboot it, even run sudo apt update just to rule out anything weird. Start with these basics before moving on to more complicated troubleshooting.
