Hi
You appear to be running an el8 (clone) and on my Rocky Linux 8 system I ran
[root@rhel8 ~]# semanage fcontext -l | grep nut_
/etc/ups(/.*)? all files
system_u:object_r:nut_conf_t:s0
/sbin/upsdrvctl regular file
system_u:object_r:nut_upsdrvctl_exec_t:s0
/usr/lib/systemd/system/nut.* regular file
system_u:object_r:nut_unit_file_t:s0
/usr/sbin/blazer_usb regular file
system_u:object_r:nut_upsdrvctl_exec_t:s0
/usr/sbin/upsd regular file
system_u:object_r:nut_upsd_exec_t:s0
/usr/sbin/upsdrvctl regular file
system_u:object_r:nut_upsdrvctl_exec_t:s0
/usr/sbin/upsmon regular file
system_u:object_r:nut_upsmon_exec_t:s0
/var/run/nut(/.*)? all files
system_u:object_r:nut_var_run_t:s0
I am wondering if your problem would just go away if you moved your FIFO
under /var/run/nut where it would automatically be assigned nut_var_run_t
Or not! :-)

SELinux is not allowing me to set the needed context on a FIFO that will be written by a nut_upsmon_t process. Runnin sesearch to find suitable types yields:
allow nut_upsmon_t nut_upsmon_t:fifo_file { append getattr ioctl lock open read write };
But, when I try to run "chcon -t nut_upsmon_t /path/to/fifo" I get "permission denied" and an SELinux alert than complains
If you want to change the label of .alertFIFO2 to nut_upsmon_t, you are not allowed to since it is not a valid file type.
Then you must pick a valid file label.
Do
select a valid file type. List valid file labels by executing:
# seinfo -afile_type -x
That returns info for files, not FIFOs.
Once again, SELinux is causing me more problems than any virus would.
