Thanks. If you used that DigitalOcean droplet from the marketplace, then I’m not sure what’s wrong. Your original command should have worked just fine.
Did you change anything in the Litespeed context settings?
One last check:
mkdir -p /usr/local/lsws/Example/html/.well-known/acme-challenge
echo 2 > /usr/local/lsws/Example/html/.well-known/acme-challenge/acme-test-2
