Hi Yohan, We have already added this but not as a JVM param but via a code, like setting in system properties. Still the issue persists.
Any other work around?

Please do not open attachments or click links from an unknown or suspicious origin. We had a similar problem. Try adding -Djava.net.preferIPv4Stack=true to the VM parameters.

Ignite cluster nodes’ OS are already on 7.8, we just upgraded client server OS. After upgrading client server, we are facing slow connections with cluster almost 5 mints. Sometimes it's not even able to connect to cluster from the client server, so had to retry multiple times. We have another client server with OS version 6.10 from which we are not facing such issue. Is there any issue compatibility issue with Red Hat 7.8 version. We are using ignite 2.7.6 version.
