RedHat systems use SELinux by default and SELinux has the habit to
block access to files, sockets, ... Especial if software from
non-Redhat repos is used.
SELinux logs to /var/log/audit/audit.log, but these logs are not easy
to understand, therefor I often use audit2allow to see which SELinux
permissions are missing.
# cat /var/log/audit/audit.log | audit2allow
You can change SELinux temporary to permissive mode so that the log will
indicate all missing permissions and not only the first few.
# setenforce 0
