There is a question on the Ru.SO that can't be opened (at least for me under Chrome and Edge) with HTTP 400 error:

I have made a dumb question on Meta.SE to reproduce this.

Question

Bad Request - Invalid URL

HTTP Error 400. The request URL is invalid.

In case of edit, direct URL can be used.

I believe it's because a "�" character in the URL of the question and the cyrillics. Only appear if the title contain both cyrillics and this character.

  • @ShadowWizard Actually, it was me. :D I just edited an original question, so it can be actually answered.

  • Oddly enough, the link works fine on the mobile app.

    @lxrec And why it shouldn't? I bet the mobile app didn't use the title as an URL and just request the title and body by API.

    Looks like some sort of block in the IIS level to me

  • The direct link to: meta.stackexchange.com/q/264085 doesn't work either.

  • "с кириллицей" == "with cyrillic" on Russian

  • @durron597 because it cause a 301 header then redirect to the bad URL.

  • @ShadowWizard half answer: It's definitely not because of "�" character as I can open another post

    @Hack really better let the team handle this, and hopefully write a post-mortem report when it's all over.

    @HackerKarma it isn't really the encoding as such; IIS (or something else in our stack) just seems to hate that codepoint - it isn't isolated.

  • Uni what is this API output? You can get the same error under dev tools 'Network' status

  • I mean to say ur JSON output HTTP error code 400 Invalid URL

  • Uni, You're giving example of API call which returns the JSON data that one can parse and render which is working on mobile app already. Whereas, Meta.SE is making a HTTP (and not API call) request here.

    I don't see what purpose this answer serves. Yes, Stack Exchange API exists and is well documented. This has nothing to do with HTTP request failure.
