Ever try loading a webpage and get greeted with a
ERR_NAME_NOT_RESOLVED? This is actually a DNS issue that could be resolved on the OS side.
On Windows, find and run
services.msc then look for "DNS Client". Right click the item and hit "Restart". Later make sure you fully close out of Chrome and reopen the webpage.
While on Linux (Ubuntu/Debian at least), you should be able to restart the DNS server by running
service bind9 restart.
