@ -95,20 +95,32 @@ Working flow:
5. all live code-server HTTP + WS traffic proxied through `/__ide/:id/*`
6. API proxies to `http://<container-ip>:8080`
Key fixes that made it work:
### Host-based IDE URL — Caddy edge (BLOCKED)
- token bootstrap fixed new-tab auth loss
- `/__ide/:id` tunnel separated from bootstrap to avoid API route interference
- upstream port corrected to `8080` (Chrome blocks `6000` as unsafe)
- `Host` header changed to pass browser host (`req.headers.host`) not container host
- `Origin` override removed — browser origin passed through only when present
- WS proxy separated from shared HTTP proxy — built target-bound WS proxy at upgrade time
- target-bound WS eliminated `ECONNREFUSED 127.0.0.1:8080` fallback bug
Goal: open IDE on `dev-<vmid>.zerolaghub.dev` instead of raw API IP.
Current state:
```
Browser → dev-6070.zerolaghub.dev → Caddy → 127.0.0.1:4000 → API
```
- browser still sees API host/IP until portal is behind a proper domain/reverse proxy
- host-based `dev-<vmid>.zlh.dev` support started but reverted — bootstrap path is canonical
State:
- API env vars set: `DEV_IDE_HOST_SUFFIX=zerolaghub.dev`, `DEV_IDE_RETURN_HOSTED_URL=true`
- API generating correct absolute URL: `http://dev-6070.zerolaghub.dev/?token=...`
- Caddyfile block correct:
```
http://dev-*.zerolaghub.dev {
@dev host dev-*.zerolaghub.dev
reverse_proxy @dev 127.0.0.1:4000
}
```
- `auto_https off` global option added
Blocking issue: browser HSTS cache forces `zerolaghub.dev` subdomains to HTTPS
regardless of Caddy config. Need to clear Chrome HSTS cache:
- `chrome://net-internals/#hsts`
- Delete `zerolaghub.dev` and `dev-6070.zerolaghub.dev`
Resume here next session.
