# \[DNS] Temporary failure resolving...

In case you have problems with DNS servers.

The error looks like this:

<figure><img src="/files/IExQflf1lwrxwasDCAPr" alt=""><figcaption></figcaption></figure>

We will show two ways to solve the problem, through SSH-access and through sFTP-access.

## Use SSH

Use the **Nano** utility to browse and edit the **resolv.conf** file where you configure our server’s **DNS**. Enter the command

```
nano /etc/resolv.conf
```

The file editor opened before us **resolv.conf**

{% hint style="info" %}
File will be empty, or it will contain text as a description, depending on the selected distribution **Linux**.
{% endhint %}

This file must specify **nameserver** for your **OS**.

{% hint style="info" %}
Which **nameserver** to choose? You can read more about this at the very end of the article. In this case, we will use **DNS 8.8.8.8** as the primary.
{% endhint %}

Enter this text in the file:

```
nameserver 8.8.8.8
nameserver 1.1.1.1
```

Press **Ctrl + X** to exit the file. Then press **Y** to save the changes.

Then press **Enter** to keep the file name as it is.

## Use sFTP

Connect to our server via **sFTP**. Next we need to go to the directory /**etc** and find there the file **resolv.conf**

<figure><img src="/files/McQRTw8k1MgDWM35qzh1" alt=""><figcaption></figcaption></figure>

Open it with any text editor.

{% hint style="info" %}
The file will be empty, or it will contain text as a description, depending on the **Linux** distribution you choose.
{% endhint %}

We need to add the optimal **nameserver** here, we will point them out several, in case of problems with one of them.

```
nameserver 8.8.8.8
nameserver 1.1.1.1
```

Great, save the file and upload it to the server.
