Did you check your network? It seems that you’re trying to connect via IPv6 (I do not see IPv4 addresses). I do not know if archive servers are reachable using IPv6.
I’ll echo @g-schick on the ip4 setup make sure in the screens before the posted one. That the IPv4 is setup properly, and saved… another check will be the date time in the bios is set correctly
I am to trying to connect via IPv4 ( assign a Static IP manually), but I also tried with IP ( automatically assigned by DHCP). Both methods give the same error. What else do I have to check?
How are you connected to the internet? What devices are used (router, …)?
Does the installer get internet connection using IPv6?
Are there other devices in the same network? If so, what are there internet connection settings?
We are connected to the internet via router. We also have a modem from the Internet service provider that is connected to the router, we also have the physical server. We are using IPv4.
