Graphics are not visible!

Dear all,

Good afternoon, I am having the following problem after installing Librenms in a virtual proxmox with ubuntu 20.04.

In simple words, I can not see the graphs, they have the legend “no data” and I would not be finding the solution. It happens with all devices.

====================================

Component Version
LibreNMS 21.12.1-21-g8f8872520
DB Schema 2021_25_01_0129_isis_adjacencies_nullable (229)
PHP 7.4.3
Python 3.8.10
MySQL 10.3.32-MariaDB-0ubuntu0.20.04.1
RRDTool 1.7.2
SNMP 5.8

====================================

[OK] Composer Version: 2.2.4
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

All devices give the same error. I don’t think they are refreshing in real time. (I don’t have an automated cron job, if you have one handy to load, you are welcome).

I leave you the reports of:

./discovery.php -h HOSTNAME -d | ./pbin.sh: Untitled - LibreNMS
./poller.php -h HOSTNAME -r -f -d | ./pbin.sh: Untitled - LibreNMS

I’ll keep waiting. Thank you.
