Hello,

The problem you are facing is related to a node who left the group, that was not able to rejoin the group and apply the missing transaction because no other available members had the missing transactions. (binlogs may also be deleted automatically (binlog_expire_logs_seconds).

The easiest solution is to migrate to 8.0.17 where members can (re-)join the cluster anyway using the clone method to transfer the data (see https://dev.mysql.com/doc/refman/8.0/en/clone-plugin.html)

Regards,
