Trying to install Overleaf Server Community Edition Toolkit following the steps in the Quick Start Guide . When I execute bin/up, I get an error:
MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017
After that, the installation goes into an endless loop.

Steps to Reproduce

Tried on Ubuntu 24.04 and 22.04 AWS EC2 instances.

Hardware requirements followed as per Hardware Requirements https://github.com/overleaf/overleaf/wiki/Hardware-Requirements .

Installed Docker packages: docker-ce, docker-ce-cli, containerd.io, docker-buildx-plugin, docker-compose-plugin.

Tried Docker versions 26 and 27.

Executed bin/init and then bin/up.

Expected Behaviour

Overleaf Community Edition installs on the server without issues.

Observed Behaviour

Here is what happened:

Context

The Overleaf server can't be installed.

Technical Info

I've verified security group settings and tried changing MongoDB from "localhost" to 127.0.0.1 and 0.0.0.0 IPs on port 27017 to no avail.
