i am new to ubuntu, apologies for the silly questions
@Sparky i am not sure how to check or allow the connections from librenms to apache @Jellyfrog i dont know how to do it, hence i posted it here for help
@Jellyfrog look for apache logs on the server and see if connections are 200 or denied from LibreNMS.
Make sure /var/cache/librenms/apache is owned by the user LibreNMS is running
