+### Troubleshooting
+
+#### 1. SQLite OOM Error (out of memory)
+
+If you see an "out of memory (14)" error from SQLite (specifically `SQLITE_CANTOPEN`), it usually means a permissions issue. The database engine cannot create temporary files in the data directory.
+
+You can fix this by setting the `PUID` and `PGID` in your `docker-compose.yml` to match your host user's UID and GID, or by manually changing the ownership of the mapped folders on your host:
+
+```bash
+# If you used a named volume (e.g., 'scriberr_scriberr_data'):
+sudo chown -R 1000:1000 /var/lib/docker/volumes/scriberr_scriberr_data/_data
+
+# If you mapped a specific host folder (e.g., ./scriberr_data):
+sudo chown -R 1000:1000 ./scriberr_data
+sudo chown -R 1000:1000 ./env_data
+```
+
+Replace `1000` with the value you set for `PUID`/`PGID` (default is `1000`).
+
+#### 2. "Unable to load audio stream"
+
+If the application loads but you cannot play or see the audio waveform (receiving "Unable to load audio stream"), this is often due to the **Secure Cookies** security flag.
+
+By default, when `APP_ENV=production`, Scriberr enables `SECURE_COOKIES=true`. This prevents cookies from being sent over insecure (HTTP) connections.
+
+**Solutions:**
+- **Recommended:** Deploy Scriberr behind a Reverse Proxy (like Nginx, Caddy, or Traefik) and use SSL/TLS (HTTPS).
+- **Alternative:** If you must access over plain HTTP, set the following environment variable in your `docker-compose.yml`:
+  ```yaml
+  environment:
+    - SECURE_COOKIES=false
+  ```
