To resolve the "This site can't provide a secure connection" message when setting up SSL for custom domains in Webflow, you can follow these steps:

  1. Verify your custom domain ownership: Ensure that you have properly completed the domain setup process and verified ownership of the domain. This involves adding the necessary DNS records provided by Webflow to your domain registrar's settings.

  2. Enable SSL in Webflow: In your Webflow project settings, go to the Hosting tab and select the custom domain you want to set up SSL for. Toggle the "SSL" switch to enable SSL for that domain.

  3. Wait for DNS propagation: It may take some time for the DNS changes to propagate across the internet. DNS propagation can take anywhere from a few minutes to 24-48 hours. Be patient and wait for the changes to propagate fully before proceeding.

  4. Check SSL status: After enabling SSL, Webflow will attempt to generate and install an SSL certificate for your custom domain. You can check the SSL status by going to the Hosting tab in your project settings and looking for the SSL certificate section. It should show the status of the SSL certificate, whether it is still pending, issued, or if there are any errors.

  5. Troubleshoot SSL errors: If you encounter any errors like "This site can't provide a secure connection" or "ERR_SSL_PROTOCOL_ERROR", it may indicate an issue with the SSL certificate. Here are a few steps to troubleshoot the issue:

  • Clear your browser cache: Sometimes, cached data can cause SSL errors. Clearing your browser cache can help resolve this issue.
  • Ensure correct DNS settings: Double-check that the DNS records for your custom domain are correctly set up in your domain registrar's settings. Make sure that you have added all the necessary DNS records provided by Webflow.
  • Contact Webflow support: If the issue persists, reach out to Webflow support for assistance. They can help troubleshoot the specific error you are encountering and provide guidance on resolving the SSL issue.
  1. Redirect HTTP to HTTPS: Once the SSL certificate is installed and working correctly, you should set up a redirect from HTTP to HTTPS. This ensures that all traffic is automatically redirected to the secure version of your website. In Webflow, you can do this by going to the Hosting tab, selecting the custom domain, and enabling the "Force HTTPS" option.

By following these steps, you should be able to resolve the "This site can't provide a secure connection" message when setting up SSL for your custom domains in Webflow.
