Hi,

since the connection fails with "connection timed out" - do you have any firewall in front of your node?
Maybe some corporate firewall that blocks outgoing connections to port 80?

Do you have firewall rules configured directly in PVE?

Could you provide output for:

cat /etc/apt/sources.list.d/pve-install-repo.list

cat /etc/apt/sources.list.d/ceph.list

cat /etc/apt/sources.list

Easier:

find /etc/apt/sources* -type f -exec cat {} +
