createCluster Fails

I have installed a fresh VM with RHEL8.
I successfully installed MySQL 8.0.25, however, whenever I try to create a cluster I get the following error message in the mysql shell:

2021-06-01 08:21:21.765604 [Error] [MY-011735] Plugin group_replication reported: '[GCS] Error connecting to the local group communication engine instance.'
2021-06-01 08:21:22.892934 [Error] [MY-011735] Plugin group_replication reported: '[GCS] The member was unable to join the group. Local port: 33061'

The log file also contains the following error message, prior to the above
2021-06-01T11:21:06.823420Z 2 [ERROR] [MY-011735] [Repl] Plugin group_replication reported: '[GCS] Unable to join the group: peers not configured. '
2021-06-01T11:21:06.823532Z 2 [ERROR] [MY-011639] [Repl] Plugin group_replication reported: 'Error on group communication engine start'
2021-06-01T11:21:06.823621Z 2 [ERROR] [MY-011735] [Repl] Plugin group_replication reported: '[GCS] The member is leaving a group without being on one.'


I've disabled the firewall, and also tried to add the machine IP address to the allows list:
set global group_replication_ip_whitelist='172.26.0.0/24,mysql1'


I've repeated this on three different VMs (all on the same subnet).

Any ideas?
