shoutcast manager autodj doesnt work

Hello everyone!
I always read the forum and this time I have come to ask for your help.
I'm testing Icecast + Autodj. Streaming works fine but autodj doesn't work. I was able to notice the following error in the following command

  systemctl status liquidsoap@17000

[My_Station:3] Connecting mount for source@localhost...
[My_Station:2] Connection failed: could not connect to host: Connection refused in connect()
[My_Station:3] Will try again in 3.00 sec.

(repeats every 3 seconds)

Does anyone know what could be wrong?
Thanks in advance

EDIT: this error happens with icecast. I am now testing with shoutcast and it works fine. The fault is with ICECAST
