Such a misconfiguration would not cause this problem.

Markup validators do not follow normal <a href=...> links; they just parse the elements (unless they can do "recursive" validation, and I don't think the W3C validator can). Besides, when the page's URL is an http: URL, this link would use the same protocol instead of using the HTTPS port 443.
When I use the validator to check the page https://residencepermitturkey.com I get one warning and two error messages very different from the one in the original post:
Error: End of file seen without seeing a doctype first. Expected <!DOCTYPE html>.
Error: Element head is missing a required instance of child element title.
Warning: Consider adding a lang attribute to the html start tag to declare the language of this document.
Something odd is going on here, since when I check "Show source", the "Source" section in te validator's response is empty, and the actual content of the page seems to be rather different: when view HTML source and cut and paste it, using "Validate by Direct Input", I get "122 Errors, 29 warning(s)".
The null source is seemingly causes by the NU validator's choice of user-agent string. If I replace it with "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 SeaMonkey/2.49.4", I can see the source just fine.
