Unable to Ping or Manage VIA GUI

Hello Everyone I've run into quiet an interesting problem. I recently wanted to rename my Proxmox to match my homes Networking Naming scheme. I made the change in the Web GUI Shell on Proxmox and simply did the reboot command from the terminal. The Server rebooted and I verified it was turned on as I have a keyboard and monitor attached to it currently. I am presented with black screen with just Proxmox login: with a blinking cursor. I didn't see the usual Welcome screen you'd get which displays the management IP along with the port.

I am unable to ping the Proxmox on its Statically assigned IP ( on the Proxmox itself I am able to ping out to, my homes gateway @ and ping numerous other hosts. But no single host on my network is able to ping the Proxmox. I have posted the results of m troubleshooting please let me know if there is anything I should change. The Proxmox was working fine for the last 5 months without issues, this is the first reboot I had done since the 5 months of it being up. I would hate to have to rebuild this all over again as I have a lot of projects in the works on this server.

System Specs:
Dell Optiplex 3080
Intel i5 3.2 ghz Quad Core
16GB Ram
1 250gb Sandisk SSD
1 256gb Samsung Evo SSD
The NIC is the onboard NIC on this device

The only time I am able to ping the is literally 1 second after I type in the reboot command into Proxmox, it will show alive for a split second, system will reboot and will boot right into Proxmox but it goes right back to being like if the IP is dead. This IP is available I have my DHCP pool setup to not assign the first 20 IPs of my network. I have tried other IPs rebooting in-between with no luck.

Here's a capture of me trying to ping while the server is rebooting. Where you see the replies(bold) is when Proxmox is going through its reboot this is right before the system reboots.
