Please format your code using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will make your post more readable. Or use markdown style like: ```` ``` CODE ``` ```` There is absolutely no code in the stacktrace coming from elasticsearch. > Connection refused Is probably the important message here. Check if elasticsearch is running and if port 9200 is accessible from your machine. ---

sorry edited. Elasticseach is running and port 9200 is accesible. If you go to 127.0.0.1:9200 it will download a json file. ---

Fixed it, bitbucket was automaticly going to port 7992. So i changed that to 9200 and now its working. Before this i had to do a lot of other stuff to even get the service running. So i am happy now, thanks for the help ---
