⚠️ Manual Steps Required

Issue: Proxmox Cluster Configuration

The pct commands are not working cluster-wide - they're looking for config files on the local node (ml110) instead of finding containers on other nodes (pve2).

Container Location: pve2 node
Container VMID: 5000
Container Status: Running
Container Hostname: blockscout-1

Solution Options

Option 1: Execute from pve2 Node (Recommended)

1. Find pve2 IP address:

   ssh root@192.168.11.10 "pvecm nodes"
   # Look for pve2 IP address
   

2. SSH to pve2:

   ssh root@<pve2-ip>
   

3. Copy scripts to pve2 (if not already there):

   # From your local machine or ml110
   scp -r /home/intlc/projects/proxmox/scripts root@<pve2-ip>:/home/intlc/projects/proxmox/
   

4. Run fix script from pve2:

   ssh root@<pve2-ip>
   cd /home/intlc/projects/proxmox
   bash scripts/fix-blockscout-explorer.sh 5000 192.168.11.140
   

Option 2: Use Proxmox Web Interface

1. Access Proxmox web UI: https://192.168.11.10:8006
2. Navigate to: pve2 → CT 5000 → Shell
3. Execute commands directly in container shell

Option 3: Configure Cluster for Cluster-Wide pct Access

This may require Proxmox cluster configuration changes (consult Proxmox documentation).

📋 Step-by-Step Manual Execution

Step 1: Verify Container Access

# Try from ml110 (may not work due to cluster issue)
ssh root@192.168.11.10
pct exec 5000 -- hostname

# If that fails, use pve2 node directly (see Option 1 above)

Step 2: Install Blockscout (if not installed)

# Check if Blockscout is installed
pct exec 5000 -- ls -la /opt/blockscout

# If not installed, copy installation script to container
pct push 5000 /path/to/blockscout-install.sh /tmp/install.sh

# Execute installation
pct exec 5000 -- bash /tmp/install.sh

# Start Blockscout service
pct exec 5000 -- systemctl start blockscout
pct exec 5000 -- systemctl enable blockscout

Step 3: Install and Configure Nginx

Method A: Using install script (run from pve2 node):

cd /home/intlc/projects/proxmox
bash scripts/install-nginx-blockscout.sh 5000 192.168.11.140

Method B: Manual installation:

# Install Nginx
pct exec 5000 -- apt-get update
pct exec 5000 -- apt-get install -y nginx

# Create SSL directory
pct exec 5000 -- mkdir -p /etc/nginx/ssl

# Generate self-signed certificate
pct exec 5000 -- openssl req -x509 -nodes -days 3650 -newkey rsa:2048 \
    -keyout /etc/nginx/ssl/blockscout.key \
    -out /etc/nginx/ssl/blockscout.crt \
    -subj '/CN=explorer.d-bis.org/O=Blockscout Explorer/C=US'

# Copy Nginx configuration
# (Use the configuration from scripts/install-nginx-blockscout.sh)
pct push 5000 /path/to/nginx-config /etc/nginx/sites-available/blockscout

# Enable site
pct exec 5000 -- ln -sf /etc/nginx/sites-available/blockscout /etc/nginx/sites-enabled/
pct exec 5000 -- rm -f /etc/nginx/sites-enabled/default

# Test and restart
pct exec 5000 -- nginx -t
pct exec 5000 -- systemctl restart nginx

Step 4: Configure Cloudflare

Using script (requires .env file with CLOUDFLARE_API_TOKEN):

cd /home/intlc/projects/proxmox
bash scripts/configure-cloudflare-explorer.sh

Manual configuration:

1. DNS Record:

   • Type: CNAME
   • Name: explorer
   • Target: <tunnel-id>.cfargotunnel.com
   • Proxy: 🟠 Proxied (orange cloud)
   • TTL: Auto

2. Tunnel Route (in Cloudflare Zero Trust):

   • Subdomain: explorer
   • Domain: d-bis.org
   • Service: http://192.168.11.140:80
   • Type: HTTP

Step 5: Test

# Test Blockscout directly
curl http://192.168.11.140:4000/api/v2/status

# Test via Nginx HTTP
curl -L http://192.168.11.140/health

# Test via Nginx HTTPS
curl -k https://192.168.11.140/health

# Test public URL (after DNS propagation)
curl https://explorer.d-bis.org/health

🔍 Troubleshooting

Issue: pct exec fails with "Configuration file does not exist"

Cause: Container is on different node (pve2) than where command is executed (ml110)

Solution: Execute commands from pve2 node or use Proxmox web interface shell

Issue: Blockscout service not found

Solution: Install Blockscout using the installation script:

pct push 5000 /path/to/smom-dbis-138-proxmox/install/blockscout-install.sh /tmp/install.sh
pct exec 5000 -- bash /tmp/install.sh

Issue: Nginx installation fails

Solution: Check container internet connectivity:

pct exec 5000 -- ping -c 3 8.8.8.8
pct exec 5000 -- apt-get update

Issue: Cloudflare 522 error persists

Solutions:

1. Verify Blockscout is running: pct exec 5000 -- curl http://localhost:4000/api/v2/status
2. Verify Nginx is running: pct exec 5000 -- systemctl status nginx
3. Check tunnel status in Cloudflare dashboard
4. Verify DNS record is proxied (orange cloud)
5. Check firewall rules allow port 80/443

📝 Summary

What Was Done:

• ✅ All fix scripts created
• ✅ Documentation complete
• ✅ Configuration files updated
• ✅ Container identified and located (pve2 node)

What Needs To Be Done:

• ⚠️ Execute scripts from pve2 node (or configure cluster properly)
• ⚠️ Install/configure Blockscout service
• ⚠️ Install/configure Nginx
• ⚠️ Configure Cloudflare DNS/tunnel
• ⚠️ Test connectivity

All scripts are ready and functional - they just need to be executed from the correct node (pve2) where the container exists, or the Proxmox cluster needs to be configured to allow cluster-wide pct command execution.
