Today I checked my $domain.error.log file in the "/var/log/apache2/domains" folder of my VestaCP installation, I got following recrods (the last 10 lines):

In these records , one is about looking for something in the folder "/etc/letsencrypt/webroot/.well-known/acme-challenge/", I think this may related to Let's Encrypt stuff, which I was implemented via this automatic LE script. So I post here, hoping someone can help me.
I have no idea what I did wrong, and how to fix them. Could you please tell me how to do?
Thank you in advance.
