esp_https_ota() fails to complete

[sramberg2]

Using IDF 4.3 I call esp_https_ota() and it never returns. Here is the log output.

It appears to have an issue with the last piece of data (70 bytes) at (14361), and will continue to output the same lines forever.

Searched through the forum and was able to find any info about this issue.

Solved the issue. Turned out to be an issue with the http server I was using.
openssl s_server -WWW -key ca_key.pem -cert ca_cert.pem -port 8070

Using the curl command as suggested in the troubleshooting section of examples\system\ota\README.MD pointed me to the issue as the curl command would only transfer the first part of the file (same number of bytes as the ESP firmware).

I am now using a python secure server suggested by this github issue: https://github.com/espressif/esp-idf/issues/5240

Hi,

I had the same issue with esp_https_ota() stuck and not completing the download.
I was using openssl:
sudo openssl s_server -WWW -key ./server_certs/ca_key.pem -cert ./server_certs/ca_cert.pem -port 8070

I changed from opessl to python server.

The solution was found at: https://github.com/espressif/esp-idf/issues/5240
