Recover kubernetes-dashboard pod?

Question

I've installed kubernetes on Ubuntu 18.04.5 LTS (Bionic Beaver). And now try to run the kubernetes-dashboard. However it keeps crashing.

NAME                                         READY   STATUS             RESTARTS   AGE
dashboard-metrics-scraper-7b59f7d4df-wj7ts   1/1     Running            0          153m

What did I miss or how can I recover from this?

TRY THE FOLLOWING

• Check kubectl get svc | grep kubernetes and then kubectl describe svc kubernetes - Correct it if there is anything wrong here.

• Define Hostname In /etc/hosts

#vim /etc/hosts
YOUR_IP HOSTNAME

• Disable Firewall
• Restart Kubelet
• Restart Docker
• Flush IP Tables
