Once you’ve added your API keys to GridPane, creating new servers should work correctly out of the box.
If, however, you’ve set up a cloud firewall at either DigitalOcean or Vultr, you may need to whitelist our IP addresses in order to spin up a server.
To whitelist us, head to your firewall setup and add the following three IP addresses to your whitelist:
18.104.22.168. At Vultr, you’ll also have to add the IPs under the API Access Control as well which you can find here: https://my.vultr.com/settings/#settingsapi
Please check out the following articles from each provider for more information regarding their firewalls.
