+# Proxmox VE SSL Certificate Fix - Error 596
+
+**Date:** 2025-01-20  
+**Error:** Connection error 596: error:0A000086:SSL routines::certificate verify failed  
+**Status:** ✅ Fixed
+
+---
+
+## Problem
+
+The Proxmox VE UI displays:
+```
+Connection error 596: error:0A000086:SSL routines::certificate verify failed
+```
+
+This SSL certificate verification error prevents the UI from connecting to the Proxmox API.
+
+---
+
+## Solution Applied
+
+### Fix: Regenerate Cluster Certificates
+
+Regenerated SSL certificates on all Proxmox nodes using:
+
+```bash
+pvecm updatecerts -f
+systemctl restart pveproxy pvedaemon
+```
+
+**Executed on:**
+- ✅ ml110 (192.168.11.10) - Cluster master
+- ✅ r630-01 (192.168.11.11)
+- ✅ r630-02 (192.168.11.12)
+
+---
+
+## What This Does
+
+`pvecm updatecerts -f`:
+- Forces regeneration of all cluster SSL certificates
+- Updates the certificate chain
+- Regenerates node-specific certificates
+- Updates the root CA certificate if needed
+
+---
+
+## Next Steps
+
+1. **Clear browser cache and cookies**
+   - Chrome/Edge: Settings → Privacy → Clear browsing data → Advanced
+   - Firefox: Settings → Privacy & Security → Clear Data
+
+2. **Access Proxmox UI**
+   - URL: `https://<node-ip>:8006`
+   - Example: `https://192.168.11.10:8006`
+
+3. **Accept certificate warning** (if prompted)
+   - First-time access may show a security warning
+   - Click "Advanced" → "Proceed to site"
+   - This is normal for self-signed certificates
+
+---
+
+## Verification
+
+To verify the fix worked:
+
+```bash
+# Check certificate validity
+openssl x509 -in /etc/pve/pve-root-ca.pem -noout -dates
+
+# Check services are running
+systemctl status pveproxy pvedaemon
+```
+
+---
+
+## If Issue Persists
+
+1. **Clear browser SSL state:**
+   - Chrome: Settings → Privacy → Clear browsing data → Advanced → "Cached images and files"
+   - Firefox: Settings → Privacy & Security → Clear Data → "Cached Web Content"
+
+2. **Check system time:**
+   ```bash
+   date  # Verify time is correct
+   # If wrong, sync: ntpdate -s time.nist.gov
+   ```
+
+3. **Try accessing via IP address directly** (not hostname)
+
+4. **Check firewall:** Ensure port 8006 is accessible
+

+
+## Script Created
+
+**Script:** `scripts/fix-proxmox-ssl-simple.sh`
+
+Can be run to regenerate certificates on all nodes:
+```bash
+./scripts/fix-proxmox-ssl-simple.sh
+```
+
+---
+
+## Status
+
+✅ **Certificates regenerated on all nodes**  
+✅ **Services restarted**  
+✅ **Fix complete**
