<p>I installed k3s on a single node. But when i try to connect to it remotly from my machine with kubectl I get the following error:</p>
<pre class="lang-sh prettyprint-override"><code>» kubectl version

<p>On the k3s server kubectl is installed and puts that out:</p>
<pre class="lang-sh prettyprint-override"><code>&gt; kubectl version

<p>I copied the k3s.yaml file from the server to my machine, renamed it to config and placed into ~/.kube/config.</p>
<p>I tried to use <code>--insecure-skip-tls-verify</code> and it works, but i don't want to use it everytime.</p>

<p>The error you are getting &quot;Unable to connect to the server: x509: certificate signed by unknown authority&quot; . It seems like you have copied only the ~/.kube/(config) file .
see the content of ~/.kube/(config) file and if that file entries of a CA root certificate , Client certificate and key entries then you need to copy all those three files also to your machine.</p>
