Api key management unresponsive - 502 Bad Gateway

Hey,

I'm having issues creating and deleting api keys.

When I go to create an api key, either through the kibana interface or dev tools, after a minute or so, I eventually get a 502 Bad Gateway response.

All other kibana and elasticsearch features seem to work fine under the same account. My account that I'm using has got superuser permissions.

After some amount of time (not sure when it occurs yet), the api keys DO seem to get removed or created, so I'm thinking it does actually perform the request, but kibana doesn't get a response back or something?

I can't find any error logs in kibana and elasticsearch related to api key invalidation or creation, only the logs relating to the request.
