 Can you check for SELinux warnings/errors in

 Have you got the setroubleshoot-server package installed?  For x86_64 it
 is part of the base repository, obviously arm may differ.  The package
 installs a "SELinux Troubleshooter" entry in the Applications/Sundry
 menu, or it can be launched via:

 # /usr/bin/python -Es /usr/bin/sealert -s

 It generates suggestions to fix SELinx issues.  Sometimes it is quite
 useful, on other occasions it just lists vast numbers of possibilities
 with little or no help.  On balance it is worth trying for when it does
 help.
