Live URL and Test URL are URL specific; they are not licensed to your domain.
Typically, the Test URL can only be reset when the Live URL's domain is changed. We recommend using a sub-domain of the Live URL's domain so that you can account for this more easily. As this is what you are wanting here, I can provide you with a courtesy reset if you are no longer using the Test URL on file. Please confirm that you want your Test URL set to: https://dev.codingjungle.com
Additionally, in the future, please feel free to submit these requests to our contact us form for our accounts team 🙂 .
