HABPanel with embedded Grafana graphs sometimes fails loading

Tags: #<Tag:0x00007f3879f87c68>

I have a strange issue with loading embedded grafana graphs and was wondering if someone could help me track it down. Loading habpanel on my desktop Chrome, everything works:

but on Habpanel (runnng on a Amazon Fire HD10), Habpanel will only load either one or the other embedded graphs with the error message “If you are seeing this Grafana has failed to load its application files”

Is this a RAM starvation issue on the tablet? I’ve seen a few other mentions of the issue, but nothing conclusive. Since it’s working on my desktop Chrome, I’m inclined to believe it’s nothing to do with reverse proxy settings or Grafana’s config.

Any ideas on where I could look further?
