This site can’t provide a secure connection - DNS and Browser issue

Hi everyone,
I read all topics with similar issue but i did not find any solution. Did someone can help me how you fix the problem with DNS and Browser. works fine but if i write i got:

This site can’t provide a secure connection sent an invalid response.

  • [Try running Windows Network Diagnostics](javascript:diagnoseErrors()).


I am sending you images how my problem looks like.
I set FTP instead @ because when i put @ my domain provider (Dynadot) show me error like this:

  • Subhost ‘@’ is not in the correct format. An example of a subhost is ‘ftp’.

Here is my site Read-Only: LINK

Try adding your A records under Domain records instead of Subdomain records at Dynadot. Example here.

There’s a guide from Dynadot here on adding A records: How do I create an A record to point my domain to an IP address? | Dynadot.

Worth a try, hope it helps.
