I have these 2 errors with the same ip address (it’s a chinese ip address). Does anyone know what he wanted to do?
{"reqId":"Fvq5tnJtgQVWczVW0h9c","remoteAddr":"60.191.38.78","app":"l10n","message":"Failed to load \/var\/www\/nextcloud\/core\/l10n\/zh_CN.json - json error code: 3","level":2,"time":"2017-01-23T05:09:39+01:00","method":"GET","url":"\/","user":"--","version":"11.0.1.2"}

Ok, then he just tried to access your main page. Did you block certain ip ranges because error 400 indicates an unauthorized access. Still it is a bit strange to get this json-localization error, do you have this problem with other localizations and legitimate users as well?
