License update fails on unknown version

Elastic Stack Elasticsearch
1

Can't seem to find this issue anywhere. We're trying to update our license and it fails with this error:

curl -XPUT "http://:9200/_license" -d @elasticsearch-license.json

{"error":{"root_cause":[{"type":"exception","reason":"Unknown license version found, please upgrade all nodes to the latest elasticsearch-license plugin"}],"type":"exception","reason":"Unknown license version found, please upgrade all nodes to the latest elasticsearch-license plugin"},"status":500}

ES and all plugins are 2.4.5 including the license version.

What is the output from _cat/plugins?v?

Any ideas? Looks pretty good to me.
