Hello everyone;
First of all, I know this topic has been opened many times. However, I still couldn't find a solution. The update problem started with the Proxmox VE 9.0 version that was previously installed on the server I use at home. Couldn't access 'http://download.proxmox.com/debian'. I downloaded the new ISO file and installed a new Proxmox on my server, but it still cannot access the free subscription repository from the first installation and therefore does not update.
Repository addresses are up to date, I closed the enterprise repository from the web interface and added the non-subscription repository (I did not make any changes manually!). Its content is available in the information below. There are no restrictions through the firewall (Opnsense), my modem or ISP. Additionally, there does not seem to be any problem with ping, curl, traceroute access from the server. Yet the update always fails. I use IPv4 for general access to the internet, I am not given an IPv6 address by the ISP.
Finally, I did not encounter any problems except for one situation that I mentioned in the details below. Since I'm in a home environment, it's not a high emergency, but I want to fix this problem. If there is a situation, action or information that I have missed, please let me know.
Note: <server-ip> <firewall-ip> <modem-ip> values have been changed by me.
If I write the apt update command as 'apt update', IP address it tries to connect to is 185.219.221.167, but if I write it as 'LANGUAGE=en_US apt update', it tries to connect to the IP address 212.224.123.70. The IP 212.224.123.70 has the address 'de.cdn.proxmox.com' but IP '185.219.221.167' does not return any addresses. So I tried the traceroute command with both IP addresses. There was no problem at the IP address 185.219.221.167, but the result was different at the address 212.224.123.70. This was the only situation that seemed abnormal to me. Is this a normal situation?
I'm waiting for your help. Thank you in advance.
Regards.
