Realtime graph not working

[email protected],

I got an issue with the realtime graph on the port tab.
It used to work some time ago, nothing changed since then.
But now the graph stays empty. The normal graph for the port works.

bash-4.2$ ./validate.php
Component | Version
--------- | -------
LibreNMS  | 1.50-10-gf30d5af
DB Schema | 2019_02_10_220000_add_dates_to_fdb (132)
PHP       | 7.2.14
MySQL     | 5.5.60-MariaDB
RRDTool   | 1.4.8
SNMP      | NET-SNMP 5.7.2

[OK]    Composer Version: 1.8.4
[OK]    Dependencies up-to-date.
[OK]    Database connection successful
[OK]    Database schema correct

I always reaad through this issue

but I have nothing like that in my conf files.


Just checked and my real time graph works.

You sure nothing changed in your network structure/librenms structure?

Real time graphs will not work if using distributed poller from external location. This is, if your librenms webserver cant reach the device, then the real time graph will not work.

Check for errors in the console or web developer tools

Nothing changed in LibreNMS, validate.php is file (see initial post).
No distributed polling.
Device ran be reached, SYSLOG, SNMP and Oxidized are working fine.
