network configuration

I recently needed to change the IP structure of my proxmox cluster. I broke the cluster and changed IPs. I have one system that has lost the vmbr0 interface which has completely caused the system to loose network access. I currently only have IPMI access. Here is info on the system: Proxmox...

Hello, I have an issue with the connection. Explanation: I installed Proxmox VE 8.3 and completed the initial setup (following the installation guide). The device rebooted and redirected me to http://192.168.x.x. The problem is that it takes a long time to load, but nothing happens — the...

Strange question, and honestly not a big deal, but just got me wondering. When I do an nslookup or a ping -a xxx.xxx.xxx.xxx, my plex LXC doesn't return a hostname. My router shows its name as UNKNOWN (where other IPs would show a hostname), even though I've confirmed the hostname within the...

I had a question about installing ProxMox. I recently installed 8.3 on a Dell R620, that has four ethernet ports, two 10G SPF and two 10G RJ45. Only the first one is connected. For some reason, it chose an unused ethernet port so the installation stopped and asked me for IP, gateway, dns...
