Shelly V1 Actions not working anymore

I have 3 Shelly V1, with action set for On or Off.

For each shelly the actions trigger another shelly via http call: http://192.168.1.2/relay/0?turn=on

The actions stopped working today with no reason.

If i paste the url above in the browser the action gets executed, it's like the http calls are not being generated anymore.

I tried downgradig from 1.14.0 to 1.13.0 but it didn't work.

Any ideas?

router reboot fixed the issue!
