esp_prov.py 崩溃

[kongshui]

ubuntu20.04
esp-idf V4.4
ESP32_LyraT

板子跑的demo是：esp-idf/examples/provisioning/legacy/softap_prov，什么都没改。
然后运行esp_prov.py崩溃
python3 esp_prov.py --transport softap --sec_ver 1 --pop abcd1234 --ssid xxxx --passphrase xxxxx

崩溃log如下：
Connecting to 192.168.4.1:80

麻烦大佬们帮忙看看是为什么？找了好久都没解决。

建议使用对应的 Provisioning APP 进行验证，见如下链接 https://www.espressif.com/zh-hans/support/download/apps
