title: Javascript "TypeError: Load Failed" error when calling "fetch" on iOS
body: <p>I'm logging JS client errors using Sentry and there's a lot of &quot;TypeError: Load failed&quot; errors. It's only occurring on iOS. I can't find anything on Google. Is this a native Javascript error or something else? What does it mean? This is separate from a seemingly related issue with &quot;TypeError: cancelled&quot;.</p>
