随机出现SSL错误导致程序卡住

[MarvinChiang]

目前我的解决方法是把./NameSilo-DDNS/DDNS restart做成定时任务 经常在日志中会各种出现SSL出错情况，类似

Traceback (most recent call last):
  File "ddns.py", line 100, in __init__
    r = httpx.get("https://www.ip138.com/", headers=self.httpHeaders, timeout=10)

    return self.send(request, auth=auth, follow_redirects=follow_redirects)

针对程序出现各种SSL错误的情况：

1. 如你举例中的File "ddns.py", line 100，这个是程序初始化时才会访问 https://www.ip138.com 。如果这里报错，说明程序没启动成功，程序启动几次。后续会考虑优化一下这里
2. 获取本机IP时的ssl报错我已经优化过，不会卡住程序运行
3. 当IP发生变动时，程序向NameSilo提交新IP时，会出现SSL错误导致程序停止，我也遇到过很多次。解决办法是配置auto_restart选项，程序会自动重启

已经解决了，原因是httpx库默认不支持低版本的TLS 1.0协议 程序v2.1.0是一个稳定的版本，新版本正在筹划支持ipv6
