Network disappearing

Hi there people,

Home someone here can give me an explanation on how to fix my issues.
I run Fedora Core 31 on my storage server and it has been running great.
My primary network card is my fiber card
Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

But after a power cut it just stopped working, I debugged for some hours I give up and post here.

I just get this no matter what i do:

$ nmcli device status
DEVICE TYPE STATE CONNECTION
enp3s0 ethernet connected enp3s0
enp2s0f0 ethernet unavailable –
enp2s0f1 ethernet unavailable –
enp4s0 ethernet unavailable –
lo loopback unmanaged –

My fiber cable is in enp2s0f1 - the cable and SFP+ module have been used for a few months without any issue - and a few reboots. My module is a 10Gtek Intel model in my card and 10Gtek Netgear model in my switch - i also have an older FS.com cable with SFP+ modules hardwired on to it, this also gives the same issue.
I have tried to build the last 3 versions of the ixgbe driver from intel, but nothing :frowning: Even did a reinstall…
In dmesg i get this

[ 7.135750] ixgbe 0000:02:00.1 enp2s0f1: detected SFP+: 8

Before i just got a detected SFP+: 6 - but still no connection. When looking back in dmesg history, it looks just like above, but next thing was that it connected.

Hope someone has some advice.

Thanks

Check whether it works or not in a Fedora live session.
If the problem persists, its cause is likely the hardware.
If this is a link to your ISP, ask them to test it from the other side.
