PRTG data-source: Time-outs (Query error - 504: Gateway Timeout) after PRTG upgrade 25.2.108.1358 — panels show “No data”

[Di0g00]

Hello guys!
I hope you’re doing well.

After upgrading PRTG from 25.1.104.1961+ to 25.2.108.1358+, every Grafana panel that depends on the PRTG REST endpoint (/api/table.json) stops rendering. Queries now run for ~30 s and end in Query error – 504 Gateway Timeout, so all dashboards show “No data”.

Is anyone else hitting the same problem with the latest PRTG build? Have you found a workaround or an alternative datasource?

Worth noting: the datasource’s Save & Test succeeds and returns:

So connectivity and authentication look fine.

Thanks in advance.

Do you have any views in particular that affected you since I used a testing enviroment and it is working fine.

I've been having an issue with the 'Stat' panel, where some load and others don't—the same happens with the 'Time series' panel. For some reason, parts of my dashboard load correctly, while others don't.

But for some reason this map loads perfectly fine.

What kind of data do they pull the one's that are working and the ones that are not?

They all retrieve the same type of data. One thing I'm unsure about—and have been thinking about—is the way the assets are referenced within the panel.

For example, you have to explicitly call the entire hierarchy: Group, Host, Sensor, and Channel.

IN my case the data was still retrieved when using a wildcard

Just FYI, there is a new plugin that I am heavily testing so that I can updated grafana to version 12. https://github.com/1DeliDolu/PRTG

That sounds interesting! I’ll definitely test it as well and see how it works. Thanks for sharing!
I wanted to mention that the official Paessler PRTG already has in its Beta roadmap the development of a Grafana integration.

Paessler just released a new version. Did you experience the same issues?
