## Recommandation
|
|
If you think you have a problem with your XOA, start by typing`xoa check`command in your terminal:
|
|
|
|
```
|
|
$ xoa check
|
|
✔ Node version
|
|
✔ Disk space for /var
|
|
✔ Disk space for /
|
|
✔ XOA version
|
|
✔ xo-server config syntax
|
|
✔ Appliance registration
|
|
✔ Internet connectivity
|
|
```
|
|
If the result you have is completely different than that, or if error messages are display, lost packets, etc., you have, indeed, a problem. The next step should be to check in this document if there is an existing troubleshooting for the problem you have.
