Today certbot stops updating SSL for ours sites
Validating configuration for cloud105.itservicenet.net
… errors were found, which will prevent Let’s Encrypt from issuing a certificate :

Apache website : Apache DocumentRoot is not set to HTML directory /home/cloud105/public_html 

We always use /home/cloud105/public_html /nextcloud as we have multiple instances structured as home/cloudXXX/public_html /nextcloud

How to fix this ?
