Please post ISPConfig questions under the ISPConfig board. Please go through this LE FAQ: https://www.howtoforge.com/community/threads/lets-encrypt-error-faq.74179/
Did you add a certificate manually under SSL? If so, go to that tab, select SSL action 'Delete certificate', and then enable LE. And go through the FAQ.
