Minecraft Java Edition uses raw TCP on port 25565, not HTTP. The previous
ClusterIP Service + HTTP Ingress (Traefik 80/443) could not carry TCP 25565
traffic, so minecraft.rogi.casa:25565 was unreachable.
- Change Service to LoadBalancer with fixed IP 10.88.20.103 (dmz-pool),
matching the pihole-dns pattern, so port 25565 is exposed directly.
- Remove the dead HTTP ingress (it routed HTTP to a TCP game port).
HA runs with hostNetwork on roger-nucbox-evo-x2 while Traefik runs on the
raspberrypi node, so requests arrive at HA from 10.88.20.11. The previous
trusted_proxies entry (10.88.88.0/24) did not include this address, causing
HA to reject X-Forwarded-For and return 400 on every ingress request.
The ServiceMonitor CRD (monitoring.coreos.com) is not installed because this
cluster runs a standalone Prometheus deployment, not the Prometheus Operator.
The manifest itself noted 'only apply if Prometheus Operator is installed'.
Removing it unblocks the phoenix app sync.
The ingresses referenced a Cloudflare OriginIssuer 'prod-issuer' whose CRD
and controller are not installed in the cluster, so cert-manager could not
issue certs and Traefik served a default cert (invalid SSL). Switch to the
existing letsencrypt-prod ClusterIssuer with specific hostnames + per-app
secrets, matching the working ingresses (http-01 cannot issue wildcards).
