Just tried it again this evening on 10.2.4, and am experiencing the same thing.

406 Not Acceptable

URI not acceptable. Graph cannot respond to “127” .

The emoncms.log file just says:

2020-08-10 01:09:45.261|INFO|index.php|graph/127
2020-08-10 01:09:45.264|WARN|index.php|406 Not Acceptable|graph/127

I did some poking around and found that I needed to manually install the graph module. In the past I hadn’t been using it, my old settings.php file had
$feedviewpath = “vis/auto?feedid=”;

I didn’t think anything of that when I did the upgrade; the new one defaults to
feedviewpath = “graph/”

Which apparently doesn’t work unless you manually also install the graph module.

So, it’s working for me now. But something that I’ll need to make a note of for future upgrades.
