Hi,

192.168.201.90 8080

are you connected through a proxy? Because that local IP there in all error messages seems weird, could be a "catch all proxy" where you cannot (yet?) connect to the internet, like some public WLAN spots often do.

Can you ping some common known addresses?

ping 8.8.8.8  # google DNS
ping download.proxmox.com  # our download CDN

 

[raime20]

yes, that is the ip of the proxy.
I tried ping google and if I get a response, but download.proxmox.com is not responding

What type of proxy is this?

I tried ping google and if I get a response, but download.proxmox.com is not responding

So quite possibly a DNS issue, at least it seems like you cannot reach the configured DNS through the proxy.

Which DNS is configured? (you can check in the webinterface, Node -> DNS) or in /etc/resolv.conf.
Can you ping that one?

I already solved. The problem was in the proxy server configuration, that the proxmox IP was not configured to access the internet.
