[SOLVED] SonarQube - Elasticsearch could not bind

Last week SonarQube loaded in, worked nice and dandy. Now it throws this warning in sonar.log:

2017.03.16 11:58:47 WARN   es[o.e.bootstrap]  JNA not found. native methods will be disabled.
2017.03.16 11:58:47 INFO   es[o.elasticsearch.node]  [sonar-1489661925446] initialized
2017.03.16 11:58:47 INFO   es[o.elasticsearch.node]  [sonar-1489661925446] starting ...

Did not start of course. What could have changed while I was away?

Edit: I did not provide the logs after trying to stop Sonar
