After installing the semodule from the details, this error appears:
SELinux is preventing addconn from open access on the file /run/nm-l2tp-ipsec-163eb469-8436-4da6-a0a3-3e29f8e3c412.conf.
***** Plugin restorecon (99.5 confidence) suggests ************************
If you want to fix the label.
/run/nm-l2tp-ipsec-163eb469-8436-4da6-a0a3-3e29f8e3c412.conf default label should be var_run_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /run/nm-l2tp-ipsec-163eb469-8436-4da6-a0a3-3e29f8e3c412.conf
***** Plugin catchall (1.49 confidence) suggests **************************
If you believe that addconn should be allowed open access on the nm-l2tp-ipsec-163eb469-8436-4da6-a0a3-3e29f8e3c412.conf file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'addconn' --raw | audit2allow -M my-addconn
# semodule -i my-addconn.pp

The VPN would connect after installing the semodule again from previous details. There are 2 more SELinux errors that appear after it is established:
