# Quick Fix: Agent Can't Connect from VM

## Problem
SSL certificate errors when connecting from VM to host.

## Solution: Use HTTP on Local Network

Since the VM and host are on a trusted local network (Hyper-V), use HTTP instead of HTTPS.

### On VM - Set HTTP in Registry:

```powershell
# On VM (as Administrator):
New-Item -Path 'HKLM:\SOFTWARE\GE\ShopDB' -Force
Set-ItemProperty -Path 'HKLM:\SOFTWARE\GE\ShopDB' -Name 'BaseUrl' -Value 'http://172.31.96.1:5001'
Set-ItemProperty -Path 'HKLM:\SOFTWARE\GE\ShopDB' -Name 'CollectorKey' -Value 'shopdb_pat_b4a3fe2a01abc6bc1cb685280e65a8c35d52ec43'
```

### Test it works:

```powershell
# On VM:
curl.exe http://172.31.96.1:5001
# Should return HTML
```

### Then run the agent:

```powershell
cd C:\ProgramData\ShopDB\EndpointAgent
.\shopdb-endpoint-agent.exe --once
```

## Why HTTP is OK Here

- ✅ VM and host on same physical machine (Hyper-V)
- ✅ Traffic never leaves the host
- ✅ Hyper-V internal network is isolated
- ✅ No external network exposure

For production multi-machine deployment, use HTTPS with proper certificates.

## Alternative: Fix HTTPS (More Complex)

If you need HTTPS:

1. Export the self-signed cert from host
2. Import to VM's Trusted Root Certification Authorities
3. Use HTTPS URL
