Network not usable for proxmox

[Saccarrep]

Dear All,

I can not update my PVE installation because I can not connect to proxmox. After I'm googling here and there, it seems like the problem is related to the realtek 8169 driver of my NIC. The problem is, every solution needs me to update and then install needed software/driver. But for me, I can't even do simple apt update. I can ping google or debian, but not proxmox, that's why I'm confused. If it is the driver, I shouldn't be able to access all the websites, right? But it is only proxmox that I failed to ping.

I'm on 6.8.12-2-pve

Thank you for any of your reply.

Hi,

Could you please provide us the test ping of `download.proxmox.com`. Did you edit the `/etc/hosts` file?

Thank you for the reply.

I can ping download.proxmox.com but not www.proxmox.com nor proxmox.com (without www)
I believe I'm not editing /etc/hosts file

Yes that's right, you can only ping download.proxmox.com!

ping -c3 download.proxmox.com

Do you know the concept of HTTP/HTTPs Reverse-Proxy-Server?

I'm just a user that starting to learn, thus not yet familiar with HTTP/HTTPs Reverse-Proxy-Server.
I'm not changing any default setting. Previously I can update just fine but after recent update, I can't update anymore. My suspicion is the realtek 8169 driver of my NIC like I stated previously.
About HTTP/HTTPs Reverse-Proxy-Server, can you point out what I needed to check?

Thank you
