# Jupyter Lab Starts, but the explorer on the left is empty
This means that the gitlab repository has not been cloned properly to your user space.
One possible cause is that the spawn-link, with pre-configured parameters, did not work.
This can happen if you manually started the server, after seeing this screen:

## Solution
### 1. Shut down your Server ( File > Shut Down)
- to shutdown the server, click on `File / Shut Down` in Jupyter
and on the next page click on "Stop my Server"
<img src="assets/stop_server.png" width="400">
### 2. Wait until the server has shut down
- this may take a couple of seconds
### 3. Go back to the [repository][repo], and click the spawn link again
- after clicking the link, the server should start without asking you for any configurations
- if you see the configuration screen again, it means the spawn link did not work
- try it again, if the issue persists, get in contact with us
## Full reset
On **very rare** occasions, the git folder can be left in a broken state.
The only solution currently is to connect to taurus using a shell
and remove the broken git folder.
Login with your ZIH credentials (username and password) and remove the project's git folder.
```
ssh -A s1234567@taurus.hrsk.tu-dresden.de
mv python_datascience_2022.git python_datascience_2022.git.bak
```
- This will rename your working folder, making a backup of your changes.
- Afterwards, start again with the spawn link and the repository will be pulled again.
