### Describe your issue
Hi,
This morning I couldn’t access my server on the web, just using ssh.
It seems that nginx can not be started:
```auto
sudo yunohost service restart nginx
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.

Is it a self-signed certificate ?

No, it’s a Let’s Encrypt one.

Maybe you can try renewing it
```auto
sudo yunohost domain cert renew influxdb.arnauld.org --force
```

Try editing it
```auto
sudo nano /etc/yunohost/certs/influxdb.arnauld.org/crt.pem
```
adding
```auto
-----BEGIN CERTIFICATE-----
```
if missing.

Thank you for your help.
I solved the problem with moving the certificate, installing a self-signed one and finally getting the real Let’s Encrypt certificate.
At least I think I did this… 🙂
