Cannot add new System Recording: Unable to connect to remote asterisk

I having an issue when adding a new system recording .wav file (Admin > System Recordings). When I click on the Submit button. I got this dialog:

There was an error, See the console for more details

So i look at the Console to get more details:

Object { status: false, message: "Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)\n [/var/lib/asterisk/sounds/test-1562945124914.wav.wav]" }
recordings.js:123:14
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)
 [/var/lib/asterisk/sounds/test-1562945124914.wav.wav] recordings.js:139:13

This is what I have tried but cannot find out the solution:

• The file /var/run/asterisk/asterisk.ctl is 100% exists.
• Asterisk is running and working by make a call test.
• AMI is running by telnet to port 5038 for testing.
• service asterisk restart , systemctl restart httpd.service , reboot, re-install Recording module … does not help.

update:
I got the same issue when uploading file at Settings > Music On Hold.

Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)

Is this issue related to IPTables? Do I need to any rules to IPtables for this to work?
