Issue Description
You are trying to access a Marketo site, but keep reaching a screen telling you your browser encountered an error. These error messages include: "ERR_EMPTY_RESPONSE" or "DNS_PROBE_FINISHED_NXDOMAIN"

 

Issue Resolution

Flush the DNS Cache on your local machine. To do so:

  1. Open Windows command prompt as admin (you can do this by searching for command prompt in Windows, then right clicking it and selecting "run as administrator")
  2. Run the command: ipconfig /flushdns
  3. The command will return a simple completed message or will prompt you for another command when it is done
  4. Re-open your browser and go to the site you wanted to reach


Please note: The DNS Cache is cleared on a normal reboot too. However, the hosts file on your computer will be used during startup to put in new DNS entries, so it will never appear completely empty if you open cache.
