+## Smokescreen SSRF Proxy — Allow Private Ranges (Fixed 2026-06-11)
+
+**Symptom:** Zulip outgoing webhook to Balda fails with HTTP 407.
+Zulip logs: `client: OutgoingWebhookResponse` + "Failure! Third party responded with 407".
+
+**Root cause:** Zulip runs Smokescreen (SSRF proxy) for all outgoing HTTP.
+`host.docker.internal` resolves to a private IP (`192.168.5.x`), which Smokescreen
+blocks by default. A `docker restart` does NOT recreate containers, so env vars
+added to docker-compose aren't picked up — must use `docker compose up -d`.
+
+**Fix:** Added to `~/Developer/zulip/docker-compose.yml` under the `zulip` service env:
+
+```yaml
+PROXY_ALLOW_RANGES: "10.0.0.0/8,172.16.0.0/12,192.168.0.0/16"
+```
+
+Then recreated containers:
+
+```bash
+cd ~/Developer/zulip
+docker compose up -d
+```
+
+Smokescreen now starts with `--allow-range` flags for all RFC1918 ranges.
+Verify with: `docker exec zulip-zulip-1 ps aux | grep smokescreen`
+
+**Note:** `SETTING_ALLOW_BOTS_TO_MAKE_REQUESTS_TO_PRIVATE_ADDRESSES: "True"` was already
+set but doesn't affect Smokescreen's `--allow-range` flags — it controls a different
+check. `PROXY_ALLOW_RANGES` is the correct env var.
