After upgrading from version 10.1.3 to 10.2.3 this evening (then running the db upgrade, flushing redis, restarting Apache,) I can see that my external services are correctly sending data into my install. I can view the data on the Visualization area as well. But if I try to access a feed directly, I just get the error “Not Acceptable” in the browser, and this in the emoncms logs:
2020-07-13 02:36:04.512|WARN|index.php|406 Not Acceptable|graph/125
This is with all feeds.
How do I troubleshoot this?
