SELinux is preventing /usr/sbin/xl2tpd from read access on the file nm-xl2tpd.conf.2172.

*****  Plugin catchall (100. confidence) suggests  ***************************

If вы считаете, что xl2tpd следует разрешить доступ read к nm-xl2tpd.conf.2172 file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep xl2tpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Looks like there is a pretty good connection between the apps.

Fixed in git.
