Safari error: Safari cannot open this page because address is invalid

This Safari error (“Safari cannot open this page because address is invalid”) is almost always because of a caching error.

Troubleshoot

Try the following troubleshooting steps to resolve the error.

Try the following device-level fixes before moving on to configuration changes:

Clear Safari cache: Go to Settings > Safari > Clear History and Website Data to clear your cache in Safari. This forces Safari to re-evaluate its stored redirects.
Use Private Browsing: Open a Private Browsing window in Safari to test. Safari’s Private Browsing ignores existing caching and behaviors.
Wait and retry: Sometimes, the issue is a delay in Apple's services propagating the app's installation status. Wait for 5-10 minutes after an install/uninstall cycle before testing again.

If device-level fixes don’t resolve the error, try the following configuration fix:

The error can also happen if there's a mismatch between the URI scheme defined in your app and the one entered in the Branch Dashboard.

Check your app's Info.plist: Find the URL types entry and confirm the exact string used in URL Schemes. It's case-sensitive.
Check your Branch Dashboard: Navigate to Configuration > Link Settings > URI Scheme and ensure the value there exactly matches the one from your Info.plist. A single typo will cause failure.
