AFAIK that shouldn't be possible. But, for me to find out what's going on in this case (since the unraid spinner won't disappear)
In your browser, navigate to
https://xxxxxxxxxxxxxxx.unraid.net/Apps/ca_settings
(capitalization of "Apps" is important)
Enable debugging. Then "Apply" and "Done" You'll wind up back at CA
If you spinner does NOT disappear within 5 minutes, then
cp /tmp/CA_logs/ca_log.txt /boot
then upload ca_log.txt on the flash drive here along with your diagnostics
