# When Using Nuxt Axios Proxy Mode, Axios Config's httpsAgent Injection Cannot Handle Self-Signed Certificates on the Proxy Server

<p>As of January 2, 2020</p>
<p></p>
<p>When using the proxy mode of axios with nuxt, an error occurred during connection because the target server was using a self-signed SSL certificate.</p>
<p>UNABLE_TO_VERIFY_LEAF_SIGNATURE</p>
<p></p>
<p>Referencing this:</p>
<p><a href="https://teratail.com/questions/210638">https://teratail.com/questions/210638</a></p>
<p>I created and introduced a plugin to ignore the certificate error of axios, but it didn't change anything.</p>
<p></p>
<p>Looking at the axios issue, it seems to be an unresolved issue.</p>
<p><a href="https://github.com/axios/axios/issues/1981">https://github.com/axios/axios/issues/1981</a></p>
<p></p>
<p>So, I decided to properly sign the certificate instead.</p>
