Thanks for the reply.

Yes, I can control it locally.

Mac adress is D8:0D:17:1C:76:94 and hardware is 2.0

About the remote control, yes it shows in settings page. Below is the first kind of error when try to enable it:

About 3-4 times repeating to enable it, then it disables completely:

Yes, both are in the same network

Ok, I will wait for the engineer contact

Thanks

What was the fix?

@Zan 

Changing the DNS was the first fix suggested, but did not work. I tried by myself using a vpn, then both things worked [firmware upgrade and remote control].

I do not use vpn regularly, by the time I Iet it active for some days then I turned off, remote control kept running ok, I think by the different DNS I was used to, but about two-three weeks or a month ago the remote control stopped again, so amazon alexa could no longer control it, nor control with the app when I'm remote [locally it works fine].

Didn't have the time to go after a fix, maybe now with you bringing it up this issues could be resolved.

@Pete_29 

What's the model number, hardware version, and firmware version of your device? 

Do you have the remote control toggle in the APP? What's the error message when you try to enable it?

Please turn off the firewall on the router, change DNS to 8.8.8.8/8.8.4.4, restart the router, then try to turn on the remote control again.

If it still not working, please tell us the MAC address on the label and APP, and also the serial number on the label.

Have a good day.

I'm having the exact same issue my hs200 loses connection to the internet after the firmware update and get the exact same error message with the red exclamation. I can get it to connect to Alexa and the connection the kasa app is inconsistent.

I came to the conclusion that my router is the responsible for the problems. I can't get rid of it otherwise I'll loose the iptv from the ISP.

It suddenly gets crazy with dhcp, all appliances loose internet access, after restarting it all gets back to normal, except the HS200 remote settings/Alexa, which seems to never go back to the initial ideal setup, tried all the reset, etc, etc. Doing dhcp reservation doesn't work either.

I took one HS200 to test in a friend's home and all went fine after setup, I tested for 2 days only. So for me until I'm tied to the ISP router setup I won't have the HS200 working the remote/alexa feature.
