Synchronize module doesn`t work as expected

[LLIycTpbIu]

SUMMARY

I`m trying to play that:

    - name: copy images
      synchronize:
        mode: pull
        src: rsync://10.47.252.70/var/lib/libvirt/images/
        dest: /var/lib/libvirt/images/

and getting that kind of error:

"msg": "rsync: [Receiver] failed to connect to 10.47.252.70 (10.47.252.70): Connection timed out (110)\nrsync error: error in socket IO (code 10) at clientserver.c(139) [Receiver=3.2.7]\n"

btw, when I copy/paste command to terminal, it works fine
rsync --delay-updates -F --compress --archive --out-format='<<CHANGED>>%i %n%L' rsync://10.47.252.70/var/lib/libvirt/images/ /var/lib/libvirt/images/
