DNS issues - ScrapeStorm not detecting Atlas cluster, but works on local Docker replica

MongoDB Atlas
,
1

Hi All,

I am new to Mongo, and I think the product is great. I have a connectivity issue with Atlas, and I am seeking advice. I believe a have a security/IAM issue.

I cannot establish a connection with the cluster using commercial software. I am using ScrapeStorm, which scrapes the screen, and inserts collections into a MongoDB database.

I have the ScrapeStorm working on my local docker replica, it injects collections into the database, and I have a python changestream handler waiting for change events. It all works well. When I try to access the Atlas cluster, I cannot find a hostname that the software recognizes. I get Failed to connect to server [ec2-3.2020yadayada.compute-1.amazonaws.com.27017] error message. I added my ip-address to the Whitelist.

What works:
1-Mongo command line and Compass works, I can attach to my database.
2-The entire exporting of the data works in my docker replica set, and change steam events are working.
3-I can ping the primary in the Atlas cluster, I get alive response.

Is there any security/IAM issues that needs to be resolved?

My apologies, if this topic is already covered. If so, please provide a link to the relevant information.

Thanks
Howard

Hi Howard,

Are you connecting with the authentication and TLS context to the Atlas cluster? When you say that you can connect from the command line successfully: that’s connecting to your Atlas cluster from the exact same server that is failing to connect?

Hi, Howard.

I have the same issue in the use of the export to the Atlas cluster in the Scaprestorm tool.
When I type the host URL exactly at the top , it won’t appear an error message. but it appears the error message as I complete the input in DB name.
If I mistype the host URL, it appears an error message as soon as I focus out from the host input.
I think it is related to the Atlas authorization method to use the user name and password.
if you solve this problem. please let me know in detail.

Thanks.
