Language Tool and TexStudio

Hi! I’m executing the steps the wiki about connect Language Tool and TexStudio ( Checking (La)TeX With LanguageTool - LanguageTool Wiki ), but doesn’t work. When i run languagetool.jar and try put in webbrowser: http://localhost:8081, returns me a error:

Error: You’re using an old version of our API that’s not supported anymore. Please see “https://languagetool.org/http-api/migration.php

I read the info in the link. I’m using the newest version (3.9).
How to fix this?

Thanks a lot!

You can use http://localhost:8081/v2/check?text=foo&language=en to check whether LT is running properly - it should return a JSON document.
