It has been 10 days since I added a new property to Google Webmaster tools. Immediately an error message was displayed: "Severe health issues are found in your property" this has since disappeared by itself. But the following errors remain:
- Site errors: "Google couldn't access your site because of a DNS error."
- Lookup error: "Your DNS server did not recognize your hostname."
- Total DNS errors: "Couldn’t communicate with the DNS server."
Google is able to fetch and render my site. The robots.txt tester shows no issues and all content is allowed. Google has also cached my site. My DNS provider says the issue is not with them. I've done a DNS health check (mxtoolbox, dnsstuff, dnscheck.pingdom, dnssy). All show no errors. I've also added a sitemap, but index status is 'Pending'.
Any suggestions? How can a new property immediately show such errors? What can I do to resolve them? Has the previous owner of the domain done something strange during their ownership?
