I got this error while tryign to connect with Dev Center tool. I used the connection bundle.

I am unable to connect from spring application also. I checked the system.peers table and is empty. Is there something to do with rpc_address ? Please help

In my experience, the TransportException is almost always a result of SSL connection failures.

I'd be interested to understand how you "used the connection bundle" because I don't believe DevCenter is supported or even tested to use with Astra. I have to point out that I'm happy to be corrected if I got that wrong.

Instead we recommend you use DataStax Studio bundled with Astra. Cheers!

Hi Erick,

Yes, There seems to be an SSL issue because I am not able to ping the rpc_address of cassandra present in system.local table from local system. I am trying to connect the cassandra instance to a java application on my local machine. I followed the steps on Using Datastax Java Drivers .


Can you suggest how can I connect this cassandra instance to my local.


Thanks a lot @Erick Ramirez

Try replacing the forward slashes in the path to the secure bundle with backslashes. Also, make sure that the path is correct and that the bundle exists.

As a side note, screenshots are not helpful since we can't quote them in responses so please post the info directly here instead of screenshots. Cheers!
