I think it could still be an SELinux issue. Does putting the machine in
permissive mode, allow everything to work?
If so, then you might want to temporarily disable dontaudit rules to see
if one of them is causing your issue.
semodule -DB
Run your test
You should see lots of AVC's now. Search for ones that match your tools.
semodule -B
Will turn dontaudit rules back on.
