The FDL has been working fine in production for a few weeks and has suddenly started show this error in the browser as if it does not have a valid SSL certificate.

The FDL is generated via the API.

Is there a solution to remove this warning for my FDL?

I have raised a support request with GCP but have posted a question in here in case there is something I can do.

Turns out a received an email from Firebase about this 1 working day ago (before the weekend so I did not notice it).

I followed the instructions and several hours later it was working so I am assuming this was the issue. Note it did not fix the issue immediately.

We’re writing to let you know that your Firebase Dynamic Links (FDL) project(s) did not have configuration to prevent phishing, so we generated Allowlist URLs that your Dynamic Links can redirect to.

Specifying a URL allowlist prevents third parties from using your API key to create Dynamic Links that redirect from your FDL domain to sites not on the allowlist.

What do I need to do? Review the generated URLs or to add additional URLs:

Click 3 dot menu icon> Allowlist URL pattern from the Engage > Dynamic Links page of the Firebase console for each project. Review the auto-generated allowlist URLs to ensure they cover your intended link destinations. [Optional] Specify up to ten regular expressions for additional allowed URLs using RE2 syntax. See the images below for clarity.

Only URLs that match one of your configured regular expressions can be successfully used as a Dynamic Link's deep link or fallback link.

Your impacted project(s):

project1 project2

To learn more, see the Allow specific URL patterns documentation.

Feel free to reach out to our Firebase support team for more assistance.
