All Network inquiries are filtered from my Provider

[Halodri]

Hi,

Yes, i am new here... and i have only some experience with Linux. I already tried to solve my problem with older forum threads, but i didn't find any solutions in this forum.

I am trying to install proxmox for the first time. After the Installation i cannot update the installation. It looks like, that my provider is filtering my network inquiries from the proxmox server.



Please help me.

What‘s the actual problem, what happens when you attempt an update?

"ping www.proxmox.com" is not a good choice for a test. It does not answer to my pings too:

~$ ping -c1 -W 2  www.proxmox.com 
PING www.proxmox.com (212.224.123.69) 56(84) bytes of data.

--- www.proxmox.com ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

I am always unhappy when a public server denies echo-request via ICMP...

~$ nmap -p 80,443   www.proxmox.com 
Starting Nmap 7.93 ( https://nmap.org ) at 2026-01-19 09:06 CET

Does any outbound traffic succeed? Tell us more about your local network and give us some background information:

• pveversion -v

Basic network information:

• ip address show # currently active IP addresses on this machine
• ip route show # currently active routing table
• ip link show # currently active links
• cat /etc/network/interfaces # configuration of the network
• cat /etc/resolv.conf # DNS resolver settings
• ping -c 1 -W 1 9.9.9.9 # a simple "ping" to verify outgoing routing
• host quad9.net # a simple DNS lookup to verify reachable DNS servers
