Error "Invalid padding bytes." when adding node to cluster

You are viewing an old version of this question. View the current version here.

During the installation of mariadb columnstore, when I try to add replica node to cluster, it errors saying "Config distribution isn't successful.". When I check the logs, I see this errors where some encryption/decryption related py function shows "Invalid padding bytes." Due to this errors, the node cannot be added to cluster. How can I fix this error? Please help.
