Unable to connect to atlas mongo db from strapi - node.js

Question

I am using strapi and Mongo DB.
Am able to connect to mlab Mongo DB, but not to atlas clustered Mongo DB.
I am using following configuration in strapi config :
{
"defaultConnection": "default",
{
"connections": {
"default": {
"connector": "strapi-mongoose",
"settings": {
"client": "mongo",
"uri": "mongodb://<username>:<pwd>#mydb-shard-00-00-abcde.mongodb.net:27017,my-db-shard-00-01-abcde.mongodb.net:27017,mydb-shard-00-02-abcde.mongodb.net:27017/mydb?ssl=true&replicaSet=mydb-shard-0&authSource=admin",
},
"options": {"ssl":true}
}
}
}
Updated
It is working as expected there was mismatch in the spelling of clusters. For one of the clusters there is capital letter.

Answer 1

If you just start with new project you just need to do run
yarn create strapi-app my-strapi
then Choose your installation type
Custom (manual settings)Choose your installation type Custom (manual
settings)
Choose your main database:
SQLite
❯ Mongo
MySQL
Postgres
Database name: (my-strapi) (shows project name by default; hit enter)
Host: myproject-fcvyt.mongodb.net
+srv connection: true
Port (It will be ignored if you enable +srv): 27017 (do nothing, simply hit enter)
Username:<mongodb atlas cluster username>
Password:<mongodb atlas cluster password>
Authentication database (Maybe "admin" or blank): (leave blank hit enter)
Enable SSL connection: true

Answer 2

MongoDB atlas uri should include +srv. E.g., "mongodb+srv://<username>:<pwd>..."
*this is assuming you are using the node.js driver and MongoDB 3.6. Full doc here.

Answer 3

for reference these are the options that worked for me
Choose your default database client mongo
? Database name: server
? Host: cluster0.qcyvc.mongodb.net
? +srv connection: true
? Port (It will be ignored if you enable +srv): 27017
? Username: petros
? Password: ********
? Authentication database (Maybe "admin" or blank):
? Enable SSL connection: Yes
