libreswan "Failed to find our RSA Key"

Question

Ubuntu 20.04

Followed all the steps (twice now).

1. Created newhostkey on left and right.
2. Create a .conf file
3. Got the info from the left machine and put it in (see below)
4. Got the info from the right machine and put it in (see below)
5. service ipsec --full-restart
6. ipsec auto --add next-zabbix; ipsec auto --up next-zabbix
7. Got the errors below

133 "next-zabbix" #53: STATE_PARENT_I1: sent v2I1, expected v2R1
003 "next-zabbix" #53: Failed to find our RSA key

8. ipsec auto --add next-zabbix; ipsec auto --up next-zabbix
9. Got the errors below

133 "next-zabbix" #53: STATE_PARENT_I1: sent v2I1, expected v2R1
003 "next-zabbix" #53: Failed to find our RSA key

And finally the config file.

Config File

cat /etc/ipsec.d/zabbix.conf

What have I left out? Why can it not find it the private key? Why does it say (no private key)
