<p><strong>The issue:</strong>
For any vagrant box, whenever I run the vagrant up command, I get the following error:
<a href="https://i.sstatic.net/n6syx.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/n6syx.png" alt="Box could not be found. An unknown option was passed in to libcurl" /></a></p>
<p>This even happened when I tried the centos/7 box instead.</p>
<p><strong>What I have tried:</strong></p>
<ul>
<li>Tried having VirtualBox window open while running vagrant up command</li>
<li>Installing the latest VC Redist for my AMD64 (x64) and Also tried (x86) VC Redist.</li>
<li>Followed instructions in the following video, as a previous video of this channel resolved my CentOS 9 issue: <a href="https://www.youtube.com/watch?v=2FeqyzY4Y14" rel="nofollow noreferrer">https://www.youtube.com/watch?v=2FeqyzY4Y14</a></li>
<li>Modifying the Vagrantfile; I added a line <code>config.vm.box_download_insecure=true</code> below <code>config.vm.box</code></li>
</ul>
<p>However, the issue still persists.</p>

**The issue:**
For any vagrant box, whenever I run the vagrant up command, I get the following error:
[![Box could not be found. An unknown option was passed in to libcurl](https://i.sstatic.net/n6syx.png)](https://i.sstatic.net/n6syx.png)

This even happened when I tried the centos/7 box instead.

**What I have tried:**

* Tried having VirtualBox window open while running vagrant up command
* Installing the latest VC Redist for my AMD64 (x64) and Also tried (x86) VC Redist.
* Followed instructions in the following video, as a previous video of this channel resolved my CentOS 9 issue: <https://www.youtube.com/watch?v=2FeqyzY4Y14>
* Modifying the Vagrantfile; I added a line `config.vm.box_download_insecure=true` below `config.vm.box`

However, the issue still persists.
