We have been using librenms without any issues since early June 2019. All graphs worked, as far as I can tell, up until 10/15. Now all graphs for all devices are red boxes. No changes to the system have been made in a while.
Here is the output for the RRD Command:

I did not try to change ownership of the files listed in the validate.php output because this has always reported as a fail with no issues.
