导致该问题的主要原因是 IDF 中的 http parser 采用 strict 的方式,详见:https://github.com/espressif/esp-idf/bl ... #L429-L439
当域名中有 `_` 时会导致解析错误。

有以下建议:
1、域名中不要采用 `_`,改用 `-`
2、修改 https://github.com/espressif/esp-idf/bl ... .h#L52-L54,define HTTP_PARSER_STRICT 为 0

推荐采用方式 1。

另外,你需要采用命令 openssl s_client -showcerts -connect ssl_test.sandstar.com:2369 来获取你服务器的 CA 根证书。证书为执行该命令后,最下面的一个。用该证书内容覆盖 simple_ota_example/server_certs/ca_cert.pem 中内容。

以下为你测试服务器的 CA 根证书:

另外我想请问一下,esp32如果固件写入到flash后错误是否有处理呢?

你是说 OTA 过程中错误?OTA 过程结束后,会对下载的 bin 做 verify,有错误会导致 OTA 失败。

了解,也就是说会校验在RAM中的bin文件数据,文件烧入到flash后是不会校验的。

不是。整个 OTA bin,在升级过程中,会全部写入到 flash,全部写入完后,会对写入后的 OTA bin 做一个整体的校验。
