# Debugging inaccessible UI
|
|
|
|
The application uses the following default ports:
|
|
|
|
- **Web UI**: `20211`
|
|
- **GraphQL API**: `20212`
|
|
|
|
The **Web UI** is served by an **nginx** server, while the **API backend** runs on a **Flask (Python)** server.
|
|
|
|
## Changing Ports
|
|
|
|
- To change the **Web UI** port, update the `PORT` environment variable in the `docker-compose.yml` file.
|
|
- To change the **GraphQL API** port, use the `GRAPHQL_PORT` setting, either directly or via Docker:
|
|
```yaml
|
|
APP_CONF_OVERRIDE={"GRAPHQL_PORT":"20212"}
|
|
```
|
|
|
|
For more information, check the [Docker installation guide](./DOCKER_INSTALLATION.md).
|
|
|
|
## Possible issues and troubleshooting
|
|
|
|
Follow all of the below in order to disqualify potential causes of issues and to troubleshoot these problems faster.
|
|
|
|
### 1. Port conflicts
|
|
|
|
When opening an issue or debugging:
|
|
|
|
1. Include a screenshot of what you see when accessing `HTTP://<your rpi IP>/20211` (or your custom port)
|
|
1. [Follow steps 1, 2, 3, 4 on this page](./DEBUG_TIPS.md)
|
|
1. Execute the following in the container to see the processes and their ports and submit a screenshot of the result:
|
|
- `sudo apk add lsof`
|
|
- `sudo lsof -i`
|
|
1. Try running the `nginx` command in the container:
|
|
- if you get `nginx: [emerg] bind() to 0.0.0.0:20211 failed (98: Address in use)` try using a different port number
|
|
|
|
|
|
|
|
|
|
### 2. JavaScript issues
|
|
|
|
Check for browser console (F12 browser dev console) errors + check different browsers.
|
|
|
|
### 3. Clear the app cache and cached JavaScript files
|
|
|
|
Refresh the browser cache (usually shoft + refresh), try a private window, or different browsers. Please also refresh the app cache by clicking the 🔃 (reload) button in the header of the application.
|
|
|
|
### 4. Disable proxies
|
|
|
|
If you have any reverse proxy or similar, try disabling it.
|
|
|
|
### 5. Disable your firewall
|
|
|
|
If you are using a firewall, try to temporarily disabling it.
|
|
|
|
### 6. Post your docker start details
|
|
|
|
If you haven't, post your docker compose/run command.
|
|
|
|
### 7. Check for errors in your PHP/NGINX error logs
|
|
|
|
In the container execute and investigate:
|
|
|
|
`cat /var/log/nginx/error.log`
|
|
|
|
`cat /tmp/log/app.php_errors.log`
|
|
|
|
### 8. Make sure permissions are correct
|
|
|
|
> [!TIP]
|
|
> You can try to start the container without mapping the `/data/config` and `/data/db` dirs and if the UI shows up then the issue is most likely related to your file system permissions or file ownership.
|
|
|
|
Please read the [Permissions troubleshooting guide](./FILE_PERMISSIONS.md) and provide a screesnhot of the permissions and ownership in the `/data/db` and `app/config` directories. |
