"Invalid return_url" on REST Api authentication despite set Allowed Origins

Trello

Hi, I am getting the following error

Invalid return_url. The return URL should match the application’s allowed origins. Contact the developer.

So naturally, I would want to make sure that the return url is in the allowed origins. Here’s the request url, just in case

as I understand it, the request_url here is https:// dextend.sunshineworks.online/on-enable-authentication.html (…) and therefore the origin is https:// dextend.sunshineworks.online.

So naturally, I went to my Power-Up admin and set that.

Nonetheless, it’s still broken. It’s even more frustrating because when I test this using a non-published version of the PowerUp, it works fine.

Any ideas, please?
