    NOT resolved.
    Still Happening in Unity 2022.2.9 (SteamVR related). Exiting Unity and deleting every SteamVR reference from the project folders (using windows file explorer) then restarting Unity appears to solve it.

    Another workaround: edit SteamVR_Update.cs file on lines 22-24 and change URL's from "http" to "https".

    2022.1.10f1 this issue is still showing up. The workaround may be okay in the Editor but I'm not sure if it would work when building out to iOS. There is an old StackOverflow response saying that the NSAppTransportSecurity may be removed in the future.
