I checked in console log, it looks fine with console log. Find below lines are from console.log

But in shopify it is showing that refused to connect.
Thanks in advance
I don't know exactly what's going on, but based on the two logs you posted, the first one is a request to your app (which is normal) and the second one is actually the callback URL for after a user authorizes the app after the OAuth screen (which should only happen when a user installs / reinstalls your app). I think you're going to have to share your actual code if you need help troubleshooting this.
