+## DNS Resolution Error - `Failed to resolve 'arweave.net'`
+
+**Issue:** When running the ELT process, you encounter the following error message:
+
+```sh
+urllib3.exceptions.MaxRetryError: [...]: 
+Max retries exceeded with url: /7iN4ABrn4Mh8GMQBmryq_5AsC9VuKgyggcr5ZJ1sgEk ([...] Failed to resolve 'arweave.net'))
+```
+
+This error is most likely due to DNS resolution issues.
+
+**Solution:** To resolve DNS resolution errors, you can change your DNS server to use a more reliable option such as Cloudflare's `1.1.1.1` or Google's `8.8.8.8`. Here are instructions for changing the DNS server on different operating systems:
+
+<Tabs>
+<TabItem value="linux" label="Linux">
+
+  <ol>
+    <li>Open the terminal.</li>
+    <li>Edit the `/etc/resolv.conf` file using your preferred text editor. For example:
+      <pre><code>
+      sudo nano /etc/resolv.conf
+      </code></pre>
+      </li> 
+    <li>Add the following lines at the top of the file to set your DNS server to `1.1.1.1`:
+      <pre><code>nameserver 1.1.1.1</code></pre>
+    </li>
+    <li>Save the file and exit the text editor.</li>
+    <li>Restart your network manager or networking service to apply the changes. The command may vary depending on your Linux distribution. For example:
+      <pre><code>sudo systemctl restart network-manager</code></pre>
+    </li>
+  </ol>
+
+</TabItem>
+<TabItem value="mac" label="Mac">

+    <li>Click the "Advanced" button.</li>
+    <li>Go to the "DNS" tab.</li>
+    <li>In the "DNS Servers" section, click the "+" button and add <code>1.1.1.1</code> or <code>8.8.8.8</code>.</li>
+    <li>Click "OK" and then "Apply" to save the changes.</li>
+  </ol>
+
+</TabItem>
+<TabItem value="windows" label="Windows">
+
+  <ol>
+    <li>Open the "Control Panel."</li>
+    <li>Click on "Network and Sharing Center."</li>

+    <li>Click "Properties."</li>
+    <li>Select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties."</li>
+    <li>Choose "Use the following DNS server addresses."</li>
+    <li>Enter <code>1.1.1.1</code> as the preferred DNS server or <code>8.8.8.8</code> as an alternative DNS server.</li>
+    <li>Click "OK" to save the settings.</li>
+  </ol>
+
+</TabItem>
+</Tabs>
+

 You can connect to the [Airbyte Cloud](https://airbyte.com/airbyte-cloud) platform and try the `KYVE Source Connector`.
 
 This option does not require any local setup. For setting up a destination follow the documentation in the Airbyte cloud page. For example, the [Snowflake](elt_destinations/snowflake) section presents one such destination that could be used with cloud.
