Cannot configure group replication

this is the guide, I am using.
mysql version is Persona 8.0.30

But when I start START GROUP_REPLICATION on secondary node, this secondary node remains in RECOVERING state for a minute and the it is in ERROR state.

I checked the error log of this secondary node and:

It says in the log that you pasted above: “Authentication requires secure connection.”

Do you have SSL configured correctly on all members?
