<p>Hi I was just trying to install argo CD in my local machine. I have  installed and running minikube.</p>
<p>After creating argocd namespace, I just try these commands</p>
<pre><code>kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

</code></pre>
<p>This error persists:</p>
<pre><code>Unable to connect to the server: dial tcp [2405:200:1607:2820:41::36]:443: i/o timeout

</code></pre>
<p>Could I get some help? Byw I'm new to argo...</p>

<p>The error “<code>Unable to connect to the Server TCP I/O timeout</code>” happens usually due to some common causes and you can try to troubleshoot based on below steps :</p>
<p>1)Your Kubernetes cluster is not running. Verify that your cluster has been started, e.g. by pinging the IP address.</p>
<p>2)There are networking issues that prevent you from accessing the cluster. Verify that you can ping the IP and try to track down whether there is a firewall in place which is preventing the access.</p>
<p>3)You have configured a cluster that does not exist any more. Also error might have resulted due to the IP address difference in the kubelet configuration.</p>
<p>4)Refer to this official <a href="https://argo-cd.readthedocs.io/en/stable/developer-guide/running-locally/" rel="nofollow noreferrer">doc</a> about how to install ArgoCD  in a local machine, as mentioned in the doc you need to run in the same namespace where Argo CD is installed. Try setting the current context as the default namespace by using below steps :</p>
<pre><code>kubectl config set-context --current --namespace=argocd
</code></pre>
<p><strong>To see your current context</strong>:</p>
<p><code>kubectl config current-context</code></p>
<p><strong>To see the contexts you have</strong>:</p>
<p><code>kubectl config view</code></p>
<p><strong>To switch context</strong>:</p>
<pre><code>kubectl config use-context context-cluster-name`
</code></pre>
<p>Make sure you are using the correct kubectl context.</p>
<p>Also you can refer to this <a href="https://www.techcrumble.net/2019/06/kubernetes-error-unable-to-connect-to-the-server-tcp-i-o-timeout/" rel="nofollow noreferrer">doc</a> authored by Aruna Lakmal for more information about this error.</p>
