An app or page on your device sent a request to fallback-url.com — a placeholder URL — instead of its real backend. This is a configuration error. Depending on what the app does, requests reaching the wrong server may include sensitive information such as login credentials or personal data.
If you are the developer: search your codebase for fallback-url.com and replace it with your real backend URL. More context: forelens.com/blog/whats-your-plan-b
If you are a user: the app has a misconfigured URL. Letting the developer know would help them fix it.
