I suspect you were rejected when requesting a 50GB Dev/Test license using this link: https://splunk.com/dev-test
These licenses are only available to users who are associated with an account with a paid Splunk Enterprise or Splunk Cloud entitlement. The license approval process for 50GB Dev/Test licenses is completely automated, so if you feel this rejection was in error, you'll need to contact your Splunk sales representative.
The 10GB Developer license (available here: https://dev.splunk.com/enterprise/dev_license ) is available to everyone for non-production use - it doesn't have the same restriction as I suspect led to your rejection previously. Licenses are typically approved within 2-3 business days, but if you haven't heard back by then, please contact us at devinfo@splunk.com
