Bitbucket Pipelines and Jira Expert -- 2

We have a current bitbucket / pipeline setup and the server is hosted on WHM (ASW). The pipeline was working for deployment but now has stopped. The pipeline is getting stuck at the php artisan queue:listen Starting Laravel development server: phase of the build. So seems link a connectivity issue, however you will need to debug this. Your tasks is to work out why the build keeps stopping, and fix the issue. Any apply if you know about systems around bitbucket / pipeline setup and the server is hosted on WHM (AWS)
