Plesk Retrieve keys – open or save ‘key_update.php’

The plesk license key can be retrieved via plesk control panel

Plesk >> Server >> License Management >> Retrieve keys

Sometimes, when you click on “Retrieve keys”, you will get a download prompt to open or save the ‘key_update.php’ file.

Check the log file /usr/local/psa/admin/logs/httpsd_error_log

In case you get the error “xmlrpc_client.c:675: assertion failed”,

Restart Plesk Control Panel to perform correct startup configuration.

# /usr/local/psa/admin/bin/httpsdctl stop
# /usr/local/psa/admin/bin/httpsdctl start

# /etc/init.d/psa stop
# /etc/init.d/psa start
