I followed instructions at https://github.com/mattermost/platform/blob/master/doc/install/Amazon-Elastic-Beanstalk.md for AWS Elastic Beanstalk Setup (Docker) but, when accessing the system, I get the following warning on top of the page:
We cannot reach the Mattermost service. The service may be down or misconfigured. Please contact an administrator to make sure the WebSocket port is configured properly.
What does that imply? Is there something I need to do on EC2 instance or in EBS configuration to get things working fine?
I apologize, but this is my first experience with EBS .
Thanks in advance for your precious help
