Verification Results

Test 1: Gateway Connectivity

Status: ✅ WORKING

Test 2: DNS Resolution

Status: ⏳ TESTING (after container restart)

Test 3: Internet Connectivity

Status: ✅ WORKING

Test 4: Docker Hub Access

Status: ⏳ TESTING

---

Next Steps

1. Wait for container to fully restart (10-30 seconds)
2. Test DNS resolution again
3. Test Docker Hub connectivity
4. Attempt Docker pull for NPMplus update

If Docker Pull Still Fails

Alternative Method: Pull from Proxmox Host

Since Proxmox host has internet connectivity, pull image there and import:

# On Proxmox host (r630-01)
ssh root@r630-01

# Pull image on host
docker pull zoeyvid/npmplus:2026-01-20-r2

# Import to container's Docker
docker save zoeyvid/npmplus:2026-01-20-r2 | \
  pct exec 10233 -- docker load
