Certificate renewal error - how to delete everything and start over?

Question

Digital certificates

I can not renew the certificate, it gives an error
sudo letsencrypt renew

WARNING:letsencrypt.cli:Attempting to renew cert from /etc/letsencrypt/renewal/*******.conf produced an unexpected error: Failed authorization procedure. *********** (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://**********/.well-known/acme-challenge/KaoVyubqjwO546DG5QX50_7EZ3JbTLkC7KMtV4kRLow

How to delete everything and start over, but not with letsencrypt but with certbot?
