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
