When the URL opened, Clover shows a popup with a login form. After login correctly, the app suppose to redirect to the URL we set in the redirect_uri param but instead, the app shows "Page not Found" (notice that the footer is showing Clover).
We confirmed that our app web configuration is correct.
Previously it was working without any issue.
Is there any update related to OAuth and we need to update our implementation?
Should our webpage use HTTPS?
Thank you for letting us know! I was able to reproduce the issue. It seems to only do this when using the new Dashboard. I have submitted a ticket. For now a temporary workaround would be to use the old dashboard when testing your OAuth.
