Unable to connect to cassandra 4.0 after upgrading the spring-boot to latest 2.6.6 version


This Content is from Stack Overflow. Question asked by Shreya Sinha

I am trying to upgrade spring boot to 2.6.6 which is using spring core-5.3.18 & spring-beans is 5.3.18. But I am facing some issues with Cassandra connection , codebase is not able to establish the connection with Cassandra. The Cassandra version that we are using is 4.0.1 and driver dependencies are :


Below is the error that I am getting on server startup :

Caused by: com.datastax.oss.driver.api.core.AllNodesFailedException: Could not reach any contact point, make sure you've provided valid addresses (showing first 1 nodes, use getAllErrors() for more): Node(endPoint=/, hostId=null, hashCode=7be37940): [com.datastax.oss.driver.api.core.connection.ConnectionInitException: [s2|control|connecting...] Protocol initialization request, step 1 (OPTIONS): failed to send request (io.netty.channel.StacklessClosedChannelException)]
