READ THIS FOR FIX TO "SERVER UNRESPONSIVE" On Alexa app.

Routines on Alexa app stoppped working.

Routines stopped working Like "TV On"

Alexa would respond but would not interact with the Smartplug.

Checked Alexa app and under devices the Smartplug had "server unresponsive" indicated.

Tried rebooting echo device ,Wifi and reconnecting Smartplug to Kasa app.

Some other online help articles suggested turning off Wifi in the Kasa app.

Whilst looking for this found the problem.

THE FIX Click on "Me" bottom right Kasa App.

Select "Third Party Services"

Select "Amazon Alexa"

Select "Link Kasa to Amazon Alexa" Somehow this must have deselected during an update as the routines had previously worked.

Hope this helps.
