I always got this message pymongo.errors.ServerSelectionTimeoutError: mongo:27017: [Errno -2] Name or service not known

When I ran docker ps command I got:  and when Iran docker logs trains-mongo I got [log.txt](https://github.com/allegroai/trains-server/files/5080687/log.txt)


I already have the latest version 2.3.0.4 (46911)

now I get this error elasticsearch.exceptions.RequestError: RequestError(400, 'action_request_validation_exception', 'Validation Failed: 1: template is missing;')
