since kernel update to 5.15.XX I run into problem that my proxmox after some moments terminates all connections:
no container, vm or proxmox itself is reachable.
if I login on machine and try solve it, even ping 8.8.8.8 does not work.
I already looked into /etc/network/interfaces:
Bash: 
root@pve:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.2/24
        gateway 192.168.1.1
        bridge-ports enp1s0
        bridge-stp off
        bridge-fd 0
so, nothing suspcious here, name of my eth is "enp1s0"...

I also already looked up if it was renamed: result no it was not:
Bash: 
root@pve:~# lshw | grep -B 5 enp
                description: Ethernet interface
                product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
                vendor: Realtek Semiconductor Co., Ltd.
                physical id: 0
                bus info: pci@0000:01:00.0
                logical name: enp1s0
name matches
I attached syslog, and output if "ip address", "ip link" and "ip route".

Crazy thing is: if i reboot, select advanced boot options and boot with older kernel version (5.13.19-15) then connection works fine again.

So I cannot update my proxmox kernel anymore... any idea whats going on?

Today I tried with most recen kernel version: 5.15.74 still same problem I am 4 Months behind with Kernel verison. Can someone find out how I can reanimate my NIC Controller to works with most recent updates? or at least how to track if there is a fix for?

OK i found the interesting part in the Log,

here is similar problem: https://forum.proxmox.com/threads/n...88179_178a-transmit-queue-0-timed-out.117729/
I also tried the workaround here: (ethtook -K <interface> tso off gso off)
https://forum.proxmox.com/threads/e1000-driver-hang.58284/#post-279338
but no luck.
would be happy for any hints...

ok now i tried a workaround: I buyed a new usb ethernet adapter and installed it on proxmox:
I allocated him to another ip address and crated a new interface for him so my pve GUI is reachable now from 2 ip addresses.
it works again, fine with kenel version 5.13.19-6.
if i start it on newer kernel (5.15.74) my old problem still there, and when i try to reach proxmox usin the new USb Ethernet adapter, on browser I get no response, in syslog I see:
