In thist post I will show you how to configure your custom certificate on proxmox.

## Proxmox VE

You can do this by copying the certificate and the key to the correct files and restart the pveproxy service.

```bash
cp fullchain.pem /etc/pve/local/pveproxy-ssl.pem
cp privkey.pem /etc/pve/local/pveproxy-ssl.key

systemctl restart pveproxy
```

From the Proxmox 6 you have an option to do this by the Web UI:

> Note that the certificates key file, if provided, must NOT be password protected.

![Example image](/img/include/proxmox-cert02.webp)

## Proxmox Backup Server

```bash
cp fullchain.pem /etc/proxmox-backup/proxy.pem
cp privkey.pem /etc/proxmox-backup/proxy.key

systemctl restart proxmox-backup-proxy.service
systemctl restart proxmox-backup.service
```
