If your Domino instance enforces iFrame restrictions or a content security policy (CSP), some external content may be blocked. In these cases, your administrator must allowlist specific resources before your App can access them.
Apps may be blocked from loading content - such as fonts, APIs, or embedded pages - unless those URLs are explicitly allowlisted. Contact your Domino admin to get the URL added to the allowlist.
Identify blocked resources
To find out which external resources your App is being prevented from loading, check your browser’s developer console while the App is running.
-
Open your App in Domino and run it.
-
Once it’s running, open your browser’s web console. For example, in Chrome, use
Cmd+Option+JorCtrl+Shift+J. -
Look for errors in red, such as:
Refused to connect to https://example.com because it violates the Content Security Policy. -
Copy the URLs of any blocked resources your App depends on.
Request access
After you identify the blocked URLs, request that your administrator allowlist them so your App can load properly.
-
Send the list of URLs to your Domino administrator and request that they be allowlisted.
-
After the allowlist is updated, stop and restart your App.
-
Once restarted, the App should be able to load the required external resources.
