Current Behavior

Hello

before I can access my certificate from mounted docker config folder, but now I can't since about one month

UNRAID:~# ls -l /mnt/cache/appdata/letsencrypt/keys
total 0
lrwxrwxrwx 1 root root 27 Mar 9 12:09 cert.crt -> ./letsencrypt/fullchain.pem
lrwxrwxrwx 1 root root 25 Mar 9 12:09 cert.key -> ./letsencrypt/privkey.pem
lrwxrwxrwx 1 root root 39 Mar 9 12:09 letsencrypt -> /config/etc/letsencrypt/live/myfqdn.fr

UNRAID:~# ls -l /mnt/cache/appdata/letsencrypt/keys/letsencrypt/
/bin/ls: cannot access '/mnt/cache/appdata/letsencrypt/keys/letsencrypt/': No such file or directory

inside the container it is ok

setting the symlink for key location

rm -rf /config/keys/letsencrypt
if [[ "${ONLY_SUBDOMAINS}" = "true" ]] && [[ ! "${SUBDOMAINS}" = "wildcard" ]]; then
DOMAIN="$(echo "${SUBDOMAINS}" | tr ',' ' ' | awk '{print $1}').${URL}"
ln -s /config/etc/letsencrypt/live/"${DOMAIN}" /config/keys/letsencrypt
else
ln -s /config/etc/letsencrypt/live/"${URL}" /config/keys/letsencrypt
fi

issue because of DOMAIN place "." before the it example
if domain if one.example.com
then it will link /config/keys/letsencrypt to /config/etc/letsencrypt/live/.one.example.com

Thats why it can't check directory exist and goest in to infinity sleep
