This site returned an HTTP status code other than 200 (OK), which may cause its results to be inaccurate.

Could this be explained more in the FAQ,
and maybe with options on how to deal with that,
and how to interpret the results?

Sure, what URL did you hit and what status code and response did you get back?

@demogit-code what URL did you hit and what status code and response did you get back?

i notice this with sites behind htaccess, with for example only https, but observatory also says http problem and others

hth

Ok, so it sounds like this error gets triggered when you point observatory at a site that is served over HTTPS but not over HTTP? If so, does anyone know of an example of this that we can look at?

Hi @gene1wood ,
I am having the same issue on my personal website: https://mathieu-eustachy.com/, I do not understand why it raises this error. I am responding with an HTTP 200 when going to the mentioned url.

@Mth0158 Not, sure I'm getting a 500 when I curl your site

curl -i https://mathieu-eustachy.com/

And a 500 when I check it here : https://httpstatus.io/

@gene1wood it was my fault, the app was failing to get the HTTP Accept-Language header from your request and was therefore raising. I corrected it this morning and now it works fine. I did not think of using curl to fetch my website.

Maybe the issue was kind of the same for the author?
