Proxmox SSL Certificate Fix - Complete

Date: 2025-01-20
Error: Connection error 596: error:0A000086:SSL routines::certificate verify failed
Status: ✅ Fixed

Issue

The Proxmox VE UI showed error:

Connection error 596: error:0A000086:SSL routines::certificate verify failed

Solution Applied

Certificate Regeneration

Regenerated SSL certificates on all Proxmox cluster nodes using:

/usr/sbin/pvecm updatecerts -f
systemctl restart pveproxy pvedaemon

Nodes processed:

✅ ml110 (192.168.11.10)
✅ r630-01 (192.168.11.11)
✅ r630-02 (192.168.11.12)

Fix Script

Script: scripts/fix-proxmox-ssl-certificate-final.sh

This script:

Regenerates certificates using pvecm updatecerts -f
Restarts pveproxy and pvedaemon services
Verifies services are running
Processes all cluster nodes

What `pvecm updatecerts -f` Does

Forces regeneration of cluster SSL certificates
Updates certificate chain
Regenerates node-specific certificates
Updates root CA certificate
Syncs certificates across cluster nodes

Next Steps

Clear browser cache and cookies
- Chrome/Edge: Settings → Privacy → Clear browsing data → Advanced → "Cached images and files"
- Firefox: Settings → Privacy & Security → Clear Data → "Cached Web Content"
Access Proxmox UI
- URL: https://<node-ip>:8006
- Example: https://192.168.11.10:8006
Accept certificate warning (if prompted)
- First access may show security warning
- Click "Advanced" → "Proceed to site"
- Normal for self-signed certificates in Proxmox

Verification

Check if fix worked:

# Check certificate
openssl x509 -in /etc/pve/pve-root-ca.pem -noout -dates

# Check services
systemctl status pveproxy pvedaemon

If Issue Persists

Clear browser SSL state completely
Try accessing via IP address directly (not hostname)

Check system time synchronization:

date
# If wrong: ntpdate -s time.nist.gov

Verify firewall allows port 8006
Check services are running:
```
systemctl status pveproxy pvedaemon
```

Status

✅ Certificates regenerated on all nodes
✅ Services restarted successfully
✅ Fix complete
