very strange:
bbuser@proxy02:~/newcert$ sudo ls -l /etc/letsencrypt/archive/www.talkyoo.net | grep “Jul 10 1”
-rw-r–r-- 1 root root 1911 Jul 10 12:30 cert4.pem
-rw-r–r-- 1 root root 1647 Jul 10 12:30 chain4.pem
-rw-r–r-- 1 root root 3558 Jul 10 12:30 fullchain4.pem
the file seems missing. Or its written somewhere else.
