How to Fix SSL Certificate Error 596 on Each Proxmox Host

Error: error:0A000086:SSL routines::certificate verify failed (596)

Important: Host vs Container Commands

⚠️ These commands must be run on Proxmox HOST nodes, NOT inside containers.

pvecm updatecerts -f - Proxmox host command (not available in containers)
systemctl restart pveproxy pvedaemon - Proxmox host services (not in containers)

Method 1: Automated Script (Recommended)

Run the fix on all Proxmox host nodes automatically:

cd /home/intlc/projects/proxmox
./scripts/fix-ssl-certificate-all-hosts.sh

This will:

Connect to each Proxmox host node
Run pvecm updatecerts -f on each host
Restart pveproxy and pvedaemon services on each host
Verify services are running

Method 2: Manual Fix - One Host at a Time

For Each Proxmox Host Node:

Proxmox Host Nodes:

ml110: 192.168.11.10
r630-01: 192.168.11.11
r630-02: 192.168.11.12
r630-03: 192.168.11.13
r630-04: 192.168.11.14

Commands to run on EACH host:

# SSH to the Proxmox host (NOT a container)
ssh root@<host-ip>

# Once on the host, run:
pvecm updatecerts -f
systemctl restart pveproxy pvedaemon

# Verify services are running
systemctl status pveproxy pvedaemon

Example for ml110:

ssh root@192.168.11.10
pvecm updatecerts -f
systemctl restart pveproxy pvedaemon
systemctl status pveproxy pvedaemon
exit

Example for r630-01:

ssh root@192.168.11.11
pvecm updatecerts -f
systemctl restart pveproxy pvedaemon
systemctl status pveproxy pvedaemon
exit

Method 3: Loop Through All Hosts

Run the fix on all hosts in a loop:

# List of Proxmox host IPs
HOSTS=(
    "192.168.11.10"  # ml110
    "192.168.11.11"  # r630-01
    "192.168.11.12"  # r630-02
    "192.168.11.13"  # r630-03
    "192.168.11.14"  # r630-04
)

# Fix each host
for HOST_IP in "${HOSTS[@]}"; do
    echo "=== Fixing $HOST_IP ==="
    ssh root@"$HOST_IP" "
        pvecm updatecerts -f
        systemctl restart pveproxy pvedaemon
        systemctl status pveproxy pvedaemon --no-pager | head -5
    "
    echo ""
done

Method 4: Using pvesh (Proxmox API)

If you have API access configured:

# For each host, SSH and run:
ssh root@<host-ip> "pvecm updatecerts -f && systemctl restart pveproxy pvedaemon"

What NOT to Do

❌ Don't run these commands inside containers:

# WRONG - This won't work in a container
pct exec 100 -- pvecm updatecerts -f  # ❌ pvecm doesn't exist in containers
pct exec 100 -- systemctl restart pveproxy  # ❌ These services don't exist in containers

✅ Do run these commands on the Proxmox HOST:

# CORRECT - Run on the host itself
ssh root@192.168.11.10
pvecm updatecerts -f
systemctl restart pveproxy pvedaemon

Verification

After fixing, verify on each host:

# Check certificate
ssh root@<host-ip> "openssl x509 -in /etc/pve/pve-root-ca.pem -noout -dates"

# Check services
ssh root@<host-ip> "systemctl status pveproxy pvedaemon"

# Test web interface
curl -k -I https://<host-ip>:8006/

After Fixing All Hosts

Clear browser cache and cookies
Access Proxmox UI: https://<host-ip>:8006
Accept certificate warning if prompted (first time only)

Quick Reference

All Proxmox Host Nodes:

# Fix all hosts at once
for ip in 192.168.11.{10..14}; do
    echo "Fixing $ip..."
    ssh root@"$ip" "pvecm updatecerts -f && systemctl restart pveproxy pvedaemon"
done

Or use the automated script:

./scripts/fix-ssl-certificate-all-hosts.sh
