Workaround: Here's indication that setting net:max-retries to 2 may resolve this issue.

[student@workstation ~]$ lftp servera
lftp servera:~> set net:reconnect-interval-base 5
lftp servera:~> set net:max-retries 2
lftp servera:~> ls

Here's the manual testing which narrowed the issue down to the net:max-retries parameter in the grading script.

[student@workstation ~]$ grep max-retries /usr/local/lib/lab-troubleshootingintro
if ! lftp -e 'set net:reconnect-interval-base 5; set net:max-retries 1; ls; bye' ${target} &> /dev/null
if ! lftp -e 'set net:reconnect-interval-base 5; set net:max-retries 1; cat pub/noclip; bye' ${target} 2> /dev/null | grep -q idspispopd
