# Network Connectivity Issue

**Date:** 2026-01-31  
**Status:** OPEN  
**Severity:** Medium  

## Symptoms

- DNS resolution failing (8.8.8.8 timeout)
- Cannot connect to local services via 192.168.31.2
- curl to Gitea (port 3005) returns HTTP 000
- Git push to Gitea failing

## Affected Services

- Git push to git.xtrm-lab.org
- Potentially other services using external DNS

## Observations

- Gitea container is running (docker ps confirms)
- Ports are mapped correctly (0.0.0.0:3005->3000)
- Internal Docker IP: 172.18.0.31
- Connections from Unraid shell to local IP timing out

## Possible Causes

- Docker bridge/macvlan network issue
- iptables/firewall blocking internal traffic
- VLAN configuration affecting local routing
- DNS upstream issue

## Workaround

- Pending git commit saved locally: `dbe4699`
- Push when network is restored: `cd /tmp/infrastructure && git push`

## Next Steps

- [ ] Check iptables rules
- [ ] Verify Docker network configuration
- [ ] Check AdGuard DNS upstream settings
- [ ] Test connectivity from different network paths
