Hi Anumod,
I faced the same issue with 3.11 and I'll suggest you first go through this link to check if the new node is able to communicate back on forth on the required port with the seed node. https://support.datastax.com/hc/en-us/articles/209691483-Bootstap-fails-with-Unable-to-gossip-with-any-seeds-yet-new-node-can-connect-to-seed-nodes [http://p8.zdassets.com/hc/settings_assets/31686/200039586/dvv6wj1TrSrpmATlV5ibLw-DataStax-whitelogo.png]<https://support.datastax.com/hc/en-us/articles/209691483-Bootstap-fails-with-Unable-to-gossip-with-any-seeds-yet-new-node-can-connect-to-seed-nodes> Bootstap fails with "Unable to gossip with any seeds" yet ...<https://support.datastax.com/hc/en-us/articles/209691483-Bootstap-fails-with-Unable-to-gossip-with-any-seeds-yet-new-node-can-connect-to-seed-nodes> support.datastax.com DataStax Support; DataStax Enterprise; Install/Upgrade; Bootstap fails with "Unable to gossip with any seeds" yet new node can connect to seed nodes This will mostly be the issue but even if that is not solving your problem, check the following points: 1) Check free disk space on the seed nodes. There should be sufficient free space for data migration to the new node. 2) Check logs of the seed nodes and see if there are any errors. I found some gossip file corruption on one of the seed nodes. 3) Finally, restart server\cassandra services on the seed nodes and see if that helps. Do let me know if this solved your problem.
