Getting error when running zerotier-cli on TS-431P3 (QNAP TS-431P3)

I have tried the following:

• Disabling QuickConnect
• Disabling OpenVPN
• Restoring web port to default (5000/5001)
• Restarting NAS
• Reinstall ZT
• Checked for presence of dev/net/tun
• Verified that ZT is or is not running with ps aux | grep zerotier
• confirmed that config files exist in /var/packages/zerotier/target/var
• Issued zerotier-cli commands as root

I am aware of the following

• The GUI is deprecated and may not work on my particular NAS
• The CLI is the recommended interface for controlling ZT

Issue

I've installed ZeroTier_1.2.12_arm-x41.qpkg on my TS-431P3 NAS. I also tried the x31 and x64, but getting an error during installation that the package is not compatible.
It installs fine, and when I run zerotier-cli I also get an output. However, I cannot join a network. When I run zerotier-cli info, I get:

[/share/MD0_DATA/.qpkg/ZeroTier] # zerotier-cli info
Error connecting to the ZeroTier service: connection failed

Please check that the service is running and that TCP port 9993 can be contacted via 127.0.0.1.

When I run zerotier-one, I get a segmentation fault:

[/share/MD0_DATA/.qpkg/ZeroTier] # ./zerotier-one
Segmentation fault

The service seems to be running, but I guess it does not detect that zerotier-one is not working?

[/share/MD0_DATA/.qpkg/ZeroTier] # ps aux | grep zerotier
