Title:
Possible issue with na2.cdn.proxmox.com (95.133.229.241) refusing HTTPS connections from US East Coast
Hi,
I believe I've isolated what appears to be a problem with one CDN edge serving download.proxmox.com.
Environment:
- Proxmox VE 9
- Debian Trixie
- No-subscription repository
- East Coast US (Florida)
- Spectrum ISP
Repository configuration is the standard:
https://download.proxmox.com/debian/pve
The enterprise repository is not configured.
Symptoms
apt update intermittently reports either:
SSL connection failed: certificate verify failed
or
Could not connect to download.proxmox.com:443
Connection refused
DNS
All resolvers (local, Cloudflare, Google) resolve to:
download.proxmox.com
-> download.cdn.proxmox.com
-> us.na.cdn.proxmox.com
-> na2.cdn.proxmox.com
-> 95.133.229.241
Connectivity
The problem reproduces from multiple systems on the same network:
- macOS
- Ubuntu 24.04
- Proxmox VE host
All fail with:
curl -4 -v https://download.proxmox.com/debian/pve/
Trying 95.133.229.241:443...
Connection refused
Additional testing
I tested other CDN nodes directly:
de3.cdn.proxmox.com
and
fr.cdn.proxmox.com
Both successfully complete HTTPS connections.
Only the NA node (95.133.229.241) appears to refuse connections.
Has anyone else seen this with na2.cdn.proxmox.com?
Is there a known issue with that CDN edge or a preferred temporary workaround until it is restored?
Thanks!
