LibreNMS not displaying graph data

Tags: #<Tag:0x00007fed64519290>


I recently installed LibreNMS on Rocky OS imported the following .env, config.php, and Mysql database (librenms) everything seems to be working except for the data graph. It’s been running for over 2 days and it’s not displaying anything. It seems like it’s doing polling. Even if I add a new device no data is graphing.
