Fix problems

A page won't load

Diagnose connection errors, DNS failures, and broken pages step by step.

1 min read

Loading errors fall into a few buckets: network down, DNS broken, certificate invalid, or the site itself is offline. Walk through these in order.

Steps

Try another site
Open another known-good site. If nothing loads, your connection is the issue.
Reload without cache
Press ⇧⌘R. Step bypasses the cache for the request.
Check the address
Typos and missing https:// are the most common cause.
Disable extensions
Open an Incognito window (extensions are off). If the page loads there, an extension is interfering.
Try another DNS
macOS network settings → DNS. Switch to 1.1.1.1 or 8.8.8.8 to rule out a broken DNS.
