I had the same problem, the solution for me was to install the correspondant language package in the server (https://support.microsoft.com/en-us/help/14236/language-packs). Inmediatly after that, the validation messages started appearing in the desired language.

Do you happen to have

<globalization enableClientBasedCulture="true" uiCulture="auto" culture="auto">...</globalization>

in your web.config? This would automatically switch the culture of the site to suit the language passed via the browser request i.e. Accept-Language.

If you want to force the language from the server just set enableClientBasedCulture to false.
