My server has been encountering this issue time to time but much more encounters recently.
I only tried, manually rebooting it by holding power off then on.
This is the logs I retrieve

Hi,
it might be the issue from this thread which is likely a hardware bug. Please try the the workaround with turning off offloading mentioned there.

Thank you, I've tried that and this is the result

root@promox:~# ethtool -K eno1 tso off gso off
root@promox:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Is everything done correctly? When I input the tso off gso off nothing was prompted
 
You can check with ethtool -k eno1 if the tcp-segmentation-offload and generic-segmentation-offload settings are now off. To make it persistent, you'll need to add a post-up entry in your network configuration (see the linked post again).

Yes I've added on /etc/networking/interfaces

iface eno1 inet manual
post-up /usr/sbin/ethtool -K $IFACE tso off gso off 2> /dev/null

Did a reboot and ran
ethtool -k eno1

Tcp and generic segmentation is off
Hope this 2 can resolve otherwise will need to switch off everything
