I use a bunch of WebApps from Orion, I noticed that I have never been able to download anything from web app even after I have allowed all downloads for the site on the browser/profile/webapp. It keeps failing for some reason. This happens for every web app. There is no Firewall blocking anything Orion. My Orion app is up to date the whole time.
In the screenshots below I showed the steps I’ve done to allow download form Google Drive by allowing that website to download both on the web app and in the browser profile settings, but it just does not download. Happens to all websites that I’ve set up as a web app, not just google Drive. 


I later notice it doesn't download even on the profile browser of that web app, not just the web app itself.
Before making this post, I have tried creating a brand new profile again and creating a web app from that profile. download still failed on the profile browser level and the web app level.
The file/media actually downloads instead of failing.
