400-499 http status code

Hi there, I noticed in Bing Webmaster Tools that we get the following for the home page.These pages have 400-499 http status code. Ensuring http status 200 might help improve SERP performance and gain user traffic.I haven't seen this before, nothing comes up in Moz or Google Webmaster Tools about it.Is it worth spending time on resolving the issue, I don't see how it affects us as the page loads up perfectly but I don't understand the error.The error shows up for our home page, https : // wwww domainname comWhen checking here we get green ticks for everything sslshopper.com/ssl-checker.html

For important pages on your site, it's always important to look after the HTTP status codes especially when they're not in the 2XX range. What I would look at in a case like this is if indeed you're able to find some clues in other tools like Google Search Console or Bing Webmaster Tools. In addition, try mimicking the user agent of Google and figure out in your own browser what the type of response could be.
