Podcast Generator RSS feed not reachable to Podcast Apps

I am using a CMS for podcasting based on PHP and MySQL called Podcast Generator. And unfortunately the url of RSS feeds is not visible to any podcast apps (Overcast, BeyondPod etc), it is only possible to get the feed from a browser. How can I make it visible?

I’m sorry, any kind of automated access to websites hosted with us is not possible. Websites hosted by us can only be accessed through web browsers. You can read more about this security system here: https://infinityfree.net/support/javascript-error-using-api-or-mobile-android-app/
