Unable to connect to MongoDB from a VPN

My Mongo database is hosted on MongoDB Atlas cloud server. I am unable to connect to the server when I am on VPN(company network). When I disconnect from the VPN and try, it works fine. I have tried through multiple options, from Mongo Compass, command line, through code snippet. It’s the same problem.

I have whitelisted my public IP address on the Mongo Atlas server but still unable to connect.

On Mongo Compass I get the following error :
Connection URI : mongodb+srv://<username>:<password>@<hostname>

Error : connect ECONNREFUSED 52.42.97.161:27017

From command line : Command : mongo "mongodb://<hostname>:27017" --ssl --authenticationDatabase admin --username <username> --password <password>

Error : W NETWORK [thread1] Failed to connect to 54.148.205.233:27017 after 5000ms milliseconds, giving up.

Please let me know what I can try to make this work. Thanks!

Sounds like a firewall is blocking the ports.

Sorry if this is too basic to ask but where can I check and modify that?

@Syed_Muthahar , that’s an Amazon address so whoever manages your Amazon networking would know the answer.
