Why is the Kasa app displaying the message(s) “503 Service Temporarily Unavailable” and/or “Server internal error?”
526 03 March 2017
As of 1AM PT/03 Mar 2017, the Kasa app service was restored. Our engineering team will continue to closely monitor the system to ensure that it performs as expected.
You should now be able to use the Kasa app remote function and Amazon Alexa Voice Control to operate your TP-Link smart home products. If you’re still experiencing issues with the Kasa app, you may email the Kasa Support Team or visit TP-Link Support on the web.
We sincerely apologize for the inconvenience you experienced and appreciate your patience during yesterday’s Kasa app service interruption.
Thank you.
