Cannot load Poller Performance graphs

Good day.

I have 1 web server, 1 db server, 1 rrd storage machine and few poller machines.
I use remote rrdcached. All graphs works fine, but…

when I open the page https://librenms/poller/performance I see: in section “Total Poller Time” all graphs load for a veeery long time, in section “Total Poller Time Per Module” the graphs cannot load at all. I I browser debug tool I see 504 gateway timeout. I open a separate link to the graph, for example, https://librenms/graph.php?type=global_poller_modules_perf&legend=no&from=1526983800&to=1590055800&height=60&width=113 and I see 504 error again.
In shell at this time I see next:

Hello,

Just wanted to post here and say I am having this same issue with my Total Poller Time Per Module graphs. I get broken images and when I click on them I get Gateway Timeouts.

Since this thread is over a year old. I figured I’d ask you to see if you ever resolved your issue and if so. How did you resolve it? If it’s still an issue, hopefully someone sees this and has a clue.
