Still running MongoDB 3.4 or older? The standard VisuaLeaf installers cannot connect to your server. This page has the build that can.
VisuaLeaf's standard installers are compiled against a modern MongoDB driver, and that driver dropped support for servers below 3.6. On an older server they fail to connect rather than degrade, which is why the 3.4 build is published separately.
MongoDB 3.6 or newer
Use the standard installers — they get every release first.
Go to the main download pageMongoDB 3.4 or older
Use the build below. It is the same VisuaLeaf, not a cut-down edition.

Connect with mongosh (or the legacy mongo shell) and run:

Older releases stay online. If a deployment is pinned to a particular version, you can always download exactly that one.
MongoDB 3.4 is long past end-of-life and no longer receives security fixes from MongoDB. The 3.4 build keeps you working in the meantime, but it is a bridge rather than a destination — once your server reaches 3.6 or newer, switch to the standard installers and you will pick up releases as they ship.
