Facing the invalid configuration for my custom domain which is added to my portfolio. The domain is from Hostinger

What's different in my issue it that, the domain configuration was already done successfully. But the 'invalid configuration' happens tiem to time and when I access my domain, the defauly hostinger domain page is shown instead of the project. I have to manually go to the project's domain settings and press on 'refresh' and after 2-3 refresh it works. This is making the sharing of my domain that should point to the project, unreliable.

<!-- Code, configuration, and steps that reproduce this issue -->

<!-- Project information (URL, framework, environment, project settings) -->

The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for [bonus points](https://community.vercel.com/t/introducing-the-vercel-leaderboard/1358).

You can also use [v0](https://v0.dev/) to narrow down the possibilities.
