What is the full output of
sudo ethtool ens2f1

And how are the quality of the ethernet cables ??
You could try to swap the cables on the Win & Server , to see if the 1GB follows the cable/switch-port

This is the device we are using from LSPCI

01:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X5 40-AT2 (rev 01)

Seems like the port advertise 10G
Strange that it isnā€™t selected.

Try
sudo ethtool -s ens2f1 autoneg off speed 10000 duplex full

And if it survives :
Post output of

sudo ethtool ens2f1

We want to make sure the switch isnā€™t going into half duplex , due to autoneg off.

Is this a cable issue?
Are you using a Cat5 cable or maybe a damaged cable?

I see this question has been asked but I donā€™t see an answer.

Itā€™s possible itā€™s a cable issue. I have some cheap cat six patch cables But honestly, I suspect arenā€™t even actually cat 6. But as it was less than 1 m I thought it would be OK.
I havenā€™g tried anything new yet. I have some cat6a Cable and ends Iā€™m gonna make up my own patch cables and then try again. I just havenā€™t gotten around to it. Iā€™ll report back once I know.
