I’m not able to find the dbname, the string which i got for connection is like
mongo “mongodb+srv://sandbox.ncybb.mongodb.net/” --username m001-student
now what should i use in place of .
Capture

I have the same question. With entering test as DBname I am not able to connect to the sandbox

I get a connection refused error:

DNSHostNotFound: Failed to look up service “_mongodb._tcp.sandbox.------.mongodb.net”: Connection refused

#3

Yeah same issue with me! Hope anyone will look at it and give us the solution for it.

#4

Was able to resolve the problem. updated the system dns servers to 8.8.8.8 and worked after.

#5

Will try it, thanks for this! Happy learning

#6

Normaly this is the database (admin) where the user is saved in. Could you try this and correct me if I am wrong. Did you try this with compass before?

#7

How did you update it exactly? @Faraz_Arshad @Naman_Jain

@Debaditya_Mitra on a Mac I found the settings in System Preferences - Network - Advanced- DNS - DNS Servers

Hope it helps :slightly_smiling_face:

@Naman_Jain dbname is actually optional, if you don’t specify dbname, your connection will default to “test” db
mongo “mongodb+srv://sandbox.ncybb.mongodb.net/” --username m001-student -p
MongoDB shell version v4.4.0
connecting to: mongodb://sandbox-shard-00-00.ncybb.mongodb.net:27017 …
…
MongoDB Enterprise atlas-6nhyx4-shard-0:PRIMARY> db

to be able to use of mongo+srv URL’s your ISP’s DNS should support +SRV protocol, which most don’t yet. As @Faraz_Arshad did, you’ll need to change your DNS setting to point to a DNS server that supports it like google dns(8.8.8.8, 4.4.4.4) or opendns. this is actually mentioned in the lecture note

Not able to connect Sandbox cluster
#11

I think the reason not doing for me is because I could figure it out my Substring…XXXX?

#12

It is the DB which you want to connect to like video etc
For now you can put it as test.Even if you leave it blank as explained by Jefferson_Fermo it will connect you to test DB

#14

Would you please help me find these 5 characters XXXX?

#15

The db name is M001. The query will be
mongo “mongodb+srv://sandbox.ncybb.mongodb.net/M001” --username m001-student

Hi Taha I was wondering if you tell me where can I get this “ncybb” five character substring in my account?

#17

That would be for your own cluster. Not for Medhanie_Gebru.
