Same problem here with a C200. Just before disconnecting, Echo shows a “buffering” message, which appears to be an interruption of the image stream from Tapo. Seems to require a SW fix from TP-LINK.

the answer provided by Tapo / Tp-Link (available here - https://www.tapo.com/uk/faq/55/)

• If you are using a third-party device such as Google Home Hub, Echo Show, or fire TV to watch the live stream of the Tapo camera, it will be disconnected automatically when it arrives at a certain minute as it’s a Cloud-to-Cloud service which will strain your network bandwidth more and cause more data allowance overages. If you want to continue watching, take the Echo show as an example, you need to ask it to show again by voice command "Alexa, show me the [Camera Name]".

 

I should have the option to not be disconnected since I have an unlimited data plan... 

 

That being said, I'm returning my Tapo C200 since it can stream undefinately in Echo Show.
