--- Comment #4 from David Auer dreua@posteo.de --- AFAIK you can not edit previous messages. Just post the URLs in a new comment. Unfortunately my tries to convert your URLs to direct download weren't successful.
When I last commented I took a short peek at your spec file and if I recall correctly there are some things that need to be fixed, if you haven't already please make sure your Version/Release, License and makro usage meets the guidelines (https://docs.fedoraproject.org/en-US/packaging-guidelines/). I will try to make a full unofficial review in the next days. (I am not a packager yet so all of this is unofficial!)
I think downloading sources via curl in %setup is not allowed, but not entirely sure in this case, because it wouldn't happen for Fedora but only for rhel builds.
Additionally it would be a good idea to do a koji sratch build (also post a link when it's done) and I personally ran the fedora-review tool on my own package, it might just help you to find some mistakes and fix them yourself.
