I'm using 1GB Ubuntu 16.04 droplet to running my WordPress site. It was running fine till March 25th. But after this, it starts giving an error: "cURL error 28: Resolving timed out after 10524 milliseconds" with some of my plugins and also when I want to update any plugin. I have also contacted to the plugin author but they said it is a web host issue. So Please help me to solve this issue.
