HTTP and owin version 4.x

I have a HTTP web site and I implemented Auth0 but it does not work. I was told that owin version is the cause if the issue. I am using the latest version 4.2.2. I was told that version 4 has a bug and it is not able to support HTTP sites, only httpS. it end in a infinite loop with http site.

are you aware of this, and is there a way around this issue?

I am using .net framework 4.6.1, and my app is a webform app
