Rsyslog / CentOS 8 / no write logs|no catch

I use rsyslog (8.37.0-13) on CentOS 8 (CentOS Linux release 8.1.1911) and I've type error with my configuration.

My rsyslog.conf is :

module(load="imuxsock")
module(load="imjournal")
module(load="imtcp")
module(load="imudp")
global(workDirectory="/var/lib/rsyslog")
include(file="/etc/rsyslog.d/*.conf")
*.info;mail.none;authpriv.none;cron.none                /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
*.emerg                                                 :omusrmsg:*
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log

My subconf is :

template(name="template1" type="string" string="/data/%HOSTNAME%-%FROMHOST-IP%.log")
ruleset(name="ruleset1"){
                action(type="omfile" dynaFile="template1")
                action(type="omfwd" protocol="tcp" target="10.10.10.1" port="2020")
}
input(type="imudp" port="2020" ruleset="ruleset1")

The rsyslog check :

# rsyslogd -N1
rsyslogd: version 8.37.0-13.el8, config validation run (level 1), master config /etc/rsyslog.conf
rsyslogd: End of config validation run. Bye.

I receive logs on UDP 2020 :

But I've no logs write in /data folder and nothing forward to 10.10.10.1_TCP2020 :

# pwd
/data/
# ls -Ral

drw-r--r--. 2 root adm  6  5 mai   10:03 .
drw-r--r--. 5 root adm 50  5 mai   10:03 ..

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

if in doubt, I have disabled SELinux, but same issue.

Someone have any idea to fix it ?

Thanks

EDIT :

After all disabling SELinux, reboot, and restart services it's OK.

Now, I search to allow with Selinux. I do this :

# chcon -R --reference /var/log /data/
# chcon -R --reference /etc/rsyslog.conf /etc/rsyslog.d/
# systemctl restart rsyslog

No change …
I reboot and no change

EDIT 2 :

I've checked audit log :

# sealert -a /var/log/audit/audit.log
100% done
found 0 alerts in /var/log/audit/audit.log

EDIT 3 :

The behavior is random. After a reboot, I thought of a SELinux problem. However, having deactivated SELinux again and restarted, it no longer works. It's intriguing, I don't understand what is causing this …

EDIT 4 :

It's firewalld the problem …

                type filter hook postrouting priority 300; policy accept;

}

I'm surprised. For me, firewalld is an overlay of nftables or iptables. However, as seen in the previous commands, nothing is configured on each of them.

EDIT 5 :

After allow firewalld (but not understand because nft and iptables are empty) and allow on SELinux, I've another problem :

The new file create by rsyslog have system_u:object_r:default_t:s0 instead of system_u:object_r:var_log_t:s0. How to do so that each file created has this context?

Do you have any ideas?
