Applicable to all AX7 releases.
If you are following https://ax.help.dynamics.com/en/wiki/recurring-integrations/ to setup your recurring exports, you may notice that the download URL that the dequeue call returns is wrong. This may be caused by the load balancer in a production environment. In any case, the client code that fetches the data can use simple code to solve the issue. In C#, it would look like this:
var newDownloadLocation = new UriBuilder(dataMessage.DownloadLocation) { Scheme = Uri.UriSchemeHttps, Port = -1, };
Once the download URL is “fixed up”, download with a normal GET request.
