Hi, I have a problem as below.

I (5141) simple_ota_example: Starting OTA example
I (5141) simple_ota_example: Connected to WiFi network! Attempting to connect to
server...
E (5171) esp-tls: mbedtls_ssl_handshake returned -0x7200
I (5171) esp-tls: Certificate verified.
E (5171) esp-tls: Failed to open new connection
E (5171) TRANS_SSL: Failed to open a new connection
E (5181) HTTP_CLIENT: Connection failed, sock < 0
E (5191) esp_https_ota: Failed to open HTTP connection: ESP_ERR_HTTP_CONNECT
E (5191) simple_ota_example: Firmware upgrade failed

OK, I resolve my issue but apears next:

E (6981) esp_ota_ops: OTA image has invalid magic byte (expected 0xE9, saw 0x45
E (7001) esp_https_ota: Error: esp_ota_write failed! err=0x0
E (7001) simple_ota_example: Firmware upgrade failed

I can't find any info about this error.

It is getting better but next error is:

I (6786) esp_https_ota: Starting OTA...
I (6786) esp_https_ota: Writing to partition subtype 16 at offset 0x110000
I (6936) esp_https_ota: esp_ota_begin succeeded
I (6936) esp_https_ota: Please Wait. This may take time
I (6966) esp_https_ota: Connection closed, all data received

E (6986) esp_image: invalid segment length 0xffffffff
E (6986) esp_https_ota: Error: esp_ota_end failed! err=0x5379. Image is invalid
E (6986) simple_ota_example: Firmware upgrade failed

This expression is true: segment->data_len >= SIXTEEN_MB.
Is inside the verify_segment_header() function (esp_image_format.c file), which return return ESP_ERR_IMAGE_INVALID.

I resolved my problem.
Change version openssl from 1.1.1 to 1.0.2 helped me.

Hi filipESP,

I think I have the same problem as the one you have before. I tried the OpenSSL version 1.0.2j and 1.1.01 And run it under CMD, it doesn't work in my case. Do you mind to provide more information of how you solve your problem please?

Thanks.

Hi filipESP,

How to change version openssl from 1.1.1 to 1.0.2 under msys2?

You should to download the older version from openssl website. I don't know how to do it in CMD.

你好，我想请问一下你在这个esp-tls-mbedtls: mbedtls_ssl_handshake returned -0x7200； esp-tls: Failed to open new connection；TRANSPORT_BASE: Failed to open a new connection这些问题中你是如何解决的，可以告诉我吗，因为我也遇到了跟你一样的错误，非常感谢！！！
