I used this for deploying:

DEPLOY_HOSTNAME=eu-west-1.galaxy.meteor.com meteor deploy someurl.meteorapp.com  --settings settings.json

My settings, looks like this:

{
    "eu-west-1.galaxy.meteor.com": {
        "env": {
            "MONGO_URL": "mongodb+srv://<user>:<pw>@somedatabase-whnex.mongodb.net/test?retryWrites=true"
        }
    }
}

Using compass, I can access the database above.

What can I do ?

I do not use tjhe eu-west-part; and it works:

{
    "galaxy.meteor.com": {
        "env": {
            "ROOT_URL":"my url",
            "MONGO_URL": "mongodb://mongo url",
            "MONGO_OPLOG_URL":"mongodb://oplog url"
        }
    }}

Same here, I dont use the eu-west-1 and it works like a charm
