Multiple errors, ./validate.php

Debian 9, nginx.

Also having this exact same issue. ./validate.php tells me this:
Fail: Some folders have incorrect file permissions, this may cause issues.

Fix:
sudo chown -R librenms:librenms /opt/librenms
sudo setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
sudo chmod -R ug=rwX /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/

I run the commands, rerun validate.php, everything’s happy, check a few minutes later and get the same exact error again.

If you are seeing errors in validate, please follow the instructions in the validate.php output before posting (marked with [FIX]).

Transient files under /opt/librenms/storage/framework/ can be ignored from now. You cannot permanently fix that at this time, but the directories MUST have librenms group write access.

Additionally, most cases that cannot fixed by the prescribed fixes are different and should be in their own thread.
