Hello, I’m working for the project which uses ESP32-S3 with AWS IoT core.
Now we are facing a problem in HTTP.
When we do a HTTP GET, sometimes ESP cannot receive any data(0Byte).
This is a log line when the problem occurred.
HTTP: Response not received: Zero returned from transport recv: totalReceived=0
(This may output from the Espressif library)
It seemed to occur only when using a specific WiFi router (TP-Link deco S4), and did not occur with any other router as far as I tried.
And there is no problem when accessing the same URL from a PC or smartphone with that TP-Link router.
Do you know there are any other cases where similar problems have occurred?
Sorry if this is not the appropriate forum.
