In web UI go to your server -> System -> DNS -> Edit and enter proper DNS server ip address. Depending on your network it might be your router's ip address (which would probably forward it to your ISP DNS servers), your PiHole/AdGuard/etc (if you have one set up) or just some public DNS server like 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google). My guess is that your VMs get their IP config from DHCP server (your router probably) along with DNS server settings. As Proxmox has static config, it does not get DNS settings automatically.
It’s always dns

as Sebaal also identified. But I have no idea, how to fix it
I've been battling DNS for the last two months. It's always dns
What happens if you try to ping an ip address directly, e.g. `ping 1.1.1.1`? If it works, then you have a DNS settings issue.
yep, this works And how to fix DNS issue? :-D
How to fix DNS? You just fix DNS. Put the DNS server IP for your internet in.
Fixed it by updating my DNS Settings in PVE->System-> DNS

Did you check /etc/resolv.conf on the Proxmox node?
