Integration Issue: Shiny App with Auth0 and WordPress Website

I am currently facing an integration issue while trying to connect my Shiny app with Auth0 authentication mode (https://bushra-usman.shinyapps.io/tda_toolkit/) to my personal WordPress website (https://letthesoulwhisper.com/tda-toolkit/).

Despite following the necessary steps, there seems to be an error when sharing the link with the website developer. They were able to integrate it, but upon opening the link, we encounter a “refused to connect” message with the following error: “tda-toolkitbybushrajaved.uk.auth0.com refused to connect.”

I am seeking your expertise in resolving this connectivity problem. Your prompt assistance would be highly appreciated.

Thank you for your attention to this matter.
