We are unable to generate eInvoices on the simulation portal. ![image](https://europe1.discourse-cdn.com/flex013/uploads/zatca1/original/1X/e5c61c7248b5dbd3af5b08d627ad0871dadb5e21.png) Also the sandbox portal is not reachable, ![image](https://europe1.discourse-cdn.com/flex013/uploads/zatca1/original/1X/e8f1bd1e66f65279604f17f3f2612a86c6e44e26.png) ---

It is not only simulation, it is the whole DNS for `gw-fatoora.zatca.gov.sa` is not working. It means reporting on `simulation` or `production` is not working. Maybe domain expired, or something happened after the New Year. ---

I guess the issue has been resolved, but without indication what was the root cause. Definitely some registration (domain) or networking issue on ZATCA side.
