Autossl not working - acme not installed

Hello
i use 0.9.8.796
but admin and user could not use autossl and wait on validating status , with no error log and output result.

i try this command to sure acme was installed on my server : ls -lah /root/.acme.sh
but there is no folder , then i decide to install acme manually using below command :
$ cd /tmp/
$ git clone https://github.com/Neilpang/acme.sh.git
$ cd acme.sh/
# ./acme.sh --install

Now "ls -lah /root/.acme.sh" is ok

but problem exist yet .

how can i find log of autossl? where is store?
how can i solve this problem?
is it normal acme not installed by cwp automatically?

Best regards
