why is esp_http_client_read returning 0 during an esp_ota?
I am not sure why, but the esp_http_client_read will return 0 and even if i try 5 times to read again, it still returns 0 and then fails.
Any suggestions on how to not fail or what to do in this case?

would not enough memory cause this valid http connection to read nothing since there is nowhere to put the data?
