[SOLVED] Fresh install : connection impossible to station after some delay

[Greg_O]

Hi everybody,

I'm new user of proxmox. I tried to build a conf with proxmox in order to build a virutal machine with Home Assistant in it. I followed this tuto :
https://community.home-assistant.io/t/installing-home-assistant-os-using-proxmox-8/201835

It worked perfectly :
- prpxmox is installed and reachable
- HA was installed and reachable

But after some time (the day after); when I tried to reach the machine or my HA instance : error. None of us are still reachables.

Here is a picture of the output from the proxmox machine :


I'm totally new in proxomx and have no idea what's going on. Any idea ?

Thx

Hello Greg,

the network card you are using has some problems with pve: https://forum.proxmox.com/tags/r8169/ take a look at the posts here.

look to your web interfaces, the real ones and the virtuals.... look if you accidentally make a loop.

Hi every one,

thx for the links. I looed into it and tried something :
I understood tere xas a problem with my ethernet controller which is a Realtek Semiconductor RTL8111/8168/8411 PCI Express. But, I had driver for r8169 :

root@pve:~# lspci -v
...
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
        Subsystem: Dell RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
        Flags: bus master, fast devsel, latency 0, IRQ 16
        I/O ports at 3000 [size=256]
        Memory at d1404000 (64-bit, non-prefetchable) [size=4K]
        Memory at d1400000 (64-bit, non-prefetchable) [size=16K]

        Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Endpoint, MSI 01
        Capabilities: [b0] MSI-X: Enable+ Count=4 Masked-
        Capabilities: [100] Advanced Error Reporting

        Capabilities: [170] Latency Tolerance Reporting
        Capabilities: [178] L1 PM Substates
        Kernel driver in use: r8169
        Kernel modules: r8169
...

So, I found this tuto which helped me to change the driver to r8168 :
https://www.reddit.com/r/Proxmox/comments/150stgh/proxmox_8_rtl8169_nic_dell_micro_formfactors_in/

The only thing to do before the tuto is to be sure to have the pve-headers installed.

So, now I got the good drivers in place :

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
        Subsystem: Dell RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

        Capabilities: [178] L1 PM Substates
        Kernel driver in use: r8168
        Kernel modules: r8168

Let's hope it solved the issue. Keep you advise...
