Unable to get IP address via DHCP on HP ProLiant DL380 Gen9 with Debian
I'm having trouble getting an IP address via DHCP on my HP ProLiant DL380 Gen9 server running Debian. I've tried various troubleshooting steps, but nothing seems to work.
Error messages:
- "No DHCPOFFERS received"
- "No working leases in persistent database - sleeping"
- "Activation of network connection failed" (GNOME)
- "IP configuration unavailable" (Plasma)
Hardware:
- HP ProLiant DL380 Gen9 server
Software:
- Debian operating system
- GNOME and Plasma desktop environments
Troubleshooting steps:
- Checked network cable and ensured it's properly connected
- Restarted network service
- Set /etc/NetworkManager/NetworkManager.conf managed=true
Additional information:
- Internet worked during the Debian installation process, but not after booting into the installed system.
- The problem occurs on both GNOME and Plasma desktop environments, but Plasma provides a slightly more helpful error message.
I'd appreciate any help or guidance on resolving this issue. Has anyone else experienced similar problems with DHCP on a HP ProLiant DL380 Gen9 server with Debian?

I set the manual ipv4 to 192.168.0.72, and it says it's connected - it doesn't have any 'activation of network connection failed' error messages, but it doesn't seem to actually have any internet either
That's good. What's your routers IP address?
62.49.7.152 is my public IP, if that's what you mean. How do I use that information, other than allowing others to know my approximate location?
I'm looking for the private IP. (The one your router has on the inside network)
How do I find that? Is it written on the router somewhere, or is there a command to run to find it?
How did you set it up? Did you just plug it in and forget about it?
I didn't set it up; another member of my household did
Oh
Is your phone connected to WiFi? What do the network settings show on your phone?
Did you want a specific part of network settings, or is this helpful?
Set your gateway to 192.168.1.1. Can you then ping 1.1.1.1?
I tried changing the IP in manual settings, I'm not sure how I ping an IP, I assume it's a command that I don't know, but as the screenshots show, accessing a website didn't work. I saw an IP in the startup menu and tried that but it didn't seem to work
Your netmask should be 255.255.255.0
Why is that? I applied the change, and restarted the Ethernet connection, but I still don't have internet
Here are the network settings
