MRTG Integration with empty graphs

[kotso]

Hello,

Running latest version IXPManager and having issue with MRTG integration.

Issue is that IXPManager shows empty graphs, checking page source for graph images shows src="data:image/png;base64,"

And I have no any error in httpd error log or laravel logs.

I further investigated issue and made sure that mart itself working, to check it I just dumped one of rrd files and it contains all the data, but still all graphs shows as empty.

I would apriciate any idea/help to debug issue further.
