Mac system service Operation not permitted error

Channels DVR Server
#1

Hi folks: Maybe someone else has seen this, but there's nothing in the forum I can find.

I have installed Channels using the system service option. Today, my machine rebooted (A/C tech killed the power!), and afterward, Channels started up as a system service but I began getting errors in the log and being unable to watch using Channels.

It appears to be related to not being logged in as the user that created the system service. After I logged that user in, everything worked fine. I was thinking that user could be logged off and the service would run normally. Is that incorrect?

I have tried setting read/write permissions for everyone on the drive (chmod 777). Still has trouble. The DVR storage is an external USB3 HDD.

Any ideas? Thanks in advance!!
Mac OS 10.15.7, Channels 2021.01.15.1649, disk has 254GB free.

The errors I am receiving seem to report permissions problems. To wit:

Could not create backup: mkdir /Volumes/Channels/DVR/Database/backup-20210126.175437: operation not permitted

Couldn't create streaming directory: mkdir /Volumes/Channels/DVR/Streaming/ch6014-dANY-ip127.0.0.1-069845031: operation not permitted

Are you able to create dirs/files via Terminal yourself?

Maybe run disk utility and verify the drive filesystem?

Yes.
