# ⚠ Gitea's `[webhook] ALLOWED_HOST_LIST = external, 10.0.0.0/8` silently REJECTS headscale mesh IPs (100.64.0.0/10)

`[2026-10-01]` **⚠ Gitea's `[webhook] ALLOWED_HOST_LIST = external, 10.0.0.0/8` silently REJECTS headscale mesh IPs (100.64.0.0/10).** The test API still returns 204 and nothing arrives. The vh/arbo hook therefore targets irv-ml1's LAN `10.6.110.50:9009`; the secret was re-set and a delivery is verified (deploy ran 04:41). A Gitea webhook PATCH without `secret` and `branch_filter` drops both, so always resend them.
