Issues with ProxyPass and ProxyPassReverse when proxying to localhost and a different TCP port
A nicer way to fix this (to have your cake and eat it) with regards to SELinux is to run this command to make httpd_t types aware of the port you are using..
semanage port -a -p tcp -t http_port_t 5000
You can turn off that boolean then and still get it to work.
