I get an error when trying to connect heroku to mongodb atlas. In the logs, I do see a message on connection to db being successful but the following error happens: MongoError: (Unauthorized) not authorized on admin to execute command { listIndexes: “users”, cursor: { }, $clusterTime: { clusterTime: {1603819118 3}, signature: … It appears this was posted once in the forum but it can no longer be found. Any help to fix this would be greatly appreciated. Thanks, Roshin ---

It seems you use node.js 3.0 version, use node.js 2.2.12 heroku cannot understand “srv+mongodb://…" use “mongodb://…” instead ![image](https://us1.discourse-cdn.com/flex020/uploads/codewithmosh/original/1X/d352948efd3c0bb284fc49c641e62ca3da23c81e.png) ---

Dear Hakuhal, Thank you for your reply. It worked, I can connect and I see no errors! I was afraid if M0 free cluster limitations were the problem but that does not appear to be the case. Really appreciate it, Roshin ---

Hey, Thanks for your answer. It helped me solve Unauthorized error. However, after following the steps I got this error. ‘MongoError: seed list contains no mongos proxies, replicaset connections requires the parameter replicaSet to be supplied in the URI or options object, mongodb://server:port/db?replicaSet=name’ Help would be appreciated. My connection uri: mongodb://vidlyuser:@vidlydb-shard-00-00.wft4x.mongodb.net:27017,[vidlydb-shard-00-01.wft4x.mongodb.net:27017](http://vidlydb-shard-00-01.wft4x.mongodb.net:27017),[vidlydb-shard-00-02.wft4x.mongodb.net:27017/](http://vidlydb-shard-00-02.wft4x.mongodb.net:27017/)?ssl=true&replicaSet=atlas-13gtrm-shard-0&authSource=admin&retryWrites=true&w=majority ---

@sampreeth : I got the same error message. For me, using the Heroku CLI was removing characters after any ampersand claiming it is some command. Putting it in double quotes worked for small strings, but not large ones?! ANYWAY, I used the Heroku dashboard ([https://dashboard.heroku.com/apps/](https://dashboard.heroku.com/apps/) --\> “Settings” button --\> “Reveal Config Vars” button) to put the mongodb (the 2.2.12 connect version) string in for the “vidly\_db” key with the appropriate changes (like password and database name). I hope this fixes it for you. ---

How about authSource should I change that from admin to dbname? ---

@Ari87 I tried changing as mention. Now I’m getting. MongoError: Authentication failed. at NessageStream.messageHandler However, my dbname is correct, password is the user password. I’m stuck with this issue from 2 days. If you can help it would be really great. Thanks in advance. ---

Steps I followed to fix this issue. First, ``` npm update mongoose ``` Latest mongoose as of 5/01/2021 is mongoose 5.11.10. If there is a newer version please check the documentation. Second, If you are following mosh course. Open db.js in startup folder. Change ``` mongoose.connect(db) ``` to ``` mongoose.connect(db, {useNewUrlParser:true, useUnifiedTopology: true}) ``` Three, copy the connection string for Node driver version 2.2.12 or later. make sure the connection string does not have (mongodb+srv) copied connection string for node driver version 2.2.12 will look like as shown below. ``` mongodb://:@vidlycluster-shard-00-00.knv7y.mongodb.net:27017,vidlycluster-shard-00-01.knv7y.mongodb.net:27017,vidlycluster-shard-00-02.knv7y.mongodb.net:27017/?ssl=true&replicaSet=atlas-8ezfa5-shard-0&authSource=admin&retryWrites=true&w=majority ``` Replace “password” with the password for the “username” user. Replace “dbname” with the name of the database that connections will use by default. Once replaced, remove all the angle brackets. Four, Head over to heroku dashboad, →Settings → Click on “Reveal Config Vars” → Enter the Key as vidly\_db, value will the connection mongodb connection string. Five, Back to terminal, git add . git commit -m “Commit message” git push heroku master heroku open Hope this helps someone. It was a struggle for me to find this solution. Cheers. Ps: @Mosh Mlab is now bought by mongodb atlas. If you could update this in your course it would be really grateful. ---
