When I add my website domain: https://tayninh.gov.vn/, both of Google Search Console and Goolge Pagespeedinsights shown error like: Lighthouse returned error: FAILED_DOCUMENT_REQUEST. Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests. (Details: net::ERR_TIMED_OUT)
At first, I thought my robots.txt is wrong, but Ive checked, there is nothing wrong with it. Ive tried with Bing, they can crawl and index my website.
Please help me.
I found out the reason is our DNS config, but not the website itself. So I will close this question and find correct way to resolve this.
