Which version are you on? Exactly how did you update the license?

[hubo3085632]

es version : 2.3.5
command : curl -XPUT 'http://localhost:9200/_license' -d bo-hu.json

[Christian_Dahlqvist]

It looks like you have forgot the @ sign ahead of the file name. Try this:

curl -XPUT 'http://localhost:9200/_license' -d @bo-hu.json

It works，thank you，i forgot the @。
