@Leron-Tolmachev, I'm not sure why it's working via the Internet but not direct from HA.
Can you try triggering a different command? Like the built-in calculator command?
Also, if your command has parameters enabled, please try disabling parameters. I'm worried the "on" or "off" parameter is getting tacked on to the end of your command and messing up the command, although I'm not confident in that because if that was the problem, it should happen either way - direct from HA, or via the Internet (via the triggercmd.com cloud system).
FYI, that "Ignoring duplicate trigger" is saying it got a trigger via triggercmd.com but ignored it because it originally came from HA, and you have the direct HA integration enabled.
Can you share your command? Or ideally a screenshot from the GUI Editor? I'd like to see if I can reproduce it on my Mac.
