gossip - Group0Id mismatch

[ET]

Hello :)

I am trying to set up a scylla cluster following the official documentation: https://opensource.docs.scylladb.com/stable/operating-scylla/procedures/cluster-management/create-cluster.html .

However, I am encountering this error on the seed node: '[shard 0:goss] gossip - Group0Id mismatch from 10.0.1.192 96b2f920-0fba-11ef-bfd6-8842a7944c37 != 966638b0-0fba-11ef-a4bc-e612dcdbae52' when restarting the nodes in sequence (as instructed in the documentation). I can't quite understand what I am doing wrong here... Is it because the instances were already running in standalone before? If so, is there a way to "reset" the instances before making the join a cluster? Thank you in advanced :)
