Enable Communication Tasks

L3 Networker

Hello all


I'm trying to activate the Communication Task.

The Idea is, that User may answer without to have a xsoar account.

So far, I found this Doc:


I've entered both settings into troubleshooting.

the d1.conf file looks like:


the rights of the file looks like:

-rw-r--r-- 1 demisto demisto 26 Jun 29 10:08 d1.conf


I've restarted demisto - but do not see any port 8080 on "ss -tulpen"


What is wrong on my side? What did I overseen?






  Are you able to restart demisto like you have in the past? How are you verifying that demisto is running? Could you share the commands you're using and their output (please redact anything sensitive)?



Hello Atullo


I'll enter the following command:


sudo systemctl restart demisto | tail -f /var/log/demisto/server.log



After that I do see Logs from Demisto and wait until I see:


info Server up and running, good luck to us all


After that I do a:


systemctl status demisto


And check, If there is:


   Loaded: loaded (/etc/systemd/system/demisto.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2021-08-26 17:01:05 CEST; 2min 41s ago





PS: I just saw, that the one Demisto-Service is still in a shutdown prodecere, and is traped in a loop:

2021-08-26 17:11:53.3694 info Long running has stopped for instance [an_instance_1]

2021-08-26 17:11:54.3403 info Long running execution has stopped for instance [an_instance_1]

I'm going to reboot the machine.

reboot was done, but still no port 8080:

:~$ sudo grep BindAddress /usr/local/demisto/d1.conf
"BindAddress": ":8080",
:~$ ss -tulpen | grep 8080

You'll need to restart the XSOAR engine service on your engine (not the demisto service on your app server; my apologies, I did not word my previous questions correctly).


For engines running a Debian based distro the command would be


sudo service d1 restart


More info for starting & restarting the XSOAR engine service can be found here: Install a Cortex XSOAR Engine.




I do not have an d1 installation here. Since I'm not able to install d1-Service on Demisto machine.

"Failed - Cannot install engine along with Cortex XSOAR server"

Do I need an Engine to use those Communication Task?

If so, I need first to setup a new machine.
