Why do you get the error Can’t load URL: The domain of this URL isn’t included in the app’s domains?
When you work with Facebook Login to share your campaign on the social network, have you ever faced the error Can’t load URL: The domain of this URL isn’t included in the app’s domains that suddenly appears on a popup? The error happens because a field in the Facebook App settings contains invalid information. In other words, you have added an incorrect domain to ‘App Domain‘. It may have the wrong format or domain, or just be misspelled.

If you are looking for a fast and effective solution to this issue, you just need to follow some simple steps below. Now, let’s deal with this error!
How to Solve Can’t load URL: The domain of this URL isn’t included in the app’s domains
Here are clear instructions to solve the problem:
- Go to the Facebook for Developers page and log in.
- Access the My Apps section in the upper-right corner, then open the app you generated before.
- Click on Settings -> Basic.
- Check and edit the field ‘App Domains‘.

The domain you add to the App Domains field must not contain ‘https‘, ‘www‘, or ‘subdomain‘.
- Custom domain: the domain must be example.com
- Sharetribe subdomain: the domain will be example.sharetribe.com
Besides that, check the spelling and make sure it is correct. Once done, don’t forget to save your changes and see the results.
If Facebook Login works, congratulations. In case the error still occurs, you can try the following solution:
- Go to Client OAuth Settings.
- Enable ‘Embedded Brower OAuth Login‘ and disable ‘Use Strict Mode for Redirect URIs‘.
- Enter the redirect URI.
- Save the changes.
Finally, check the result.
