从源码自行编译的版本在tg中点击按钮报错

运行起来之后在tg中点击“正在下载”按钮，无反应

回到终端中查看发现以下报错：
```

点击“正在等待”按钮和“已完成”按钮也没反应

使用release中的版本点击“正在下载”也会报错：

但是点击“等待中”和“已停止”按钮都不会报错，不知道什么原因，源码我是自己git clone源码之后编译的版本，系统是centos7.9，另外能否增加忽略证书错误的功能，我aria2为了适应启用了https的ariang，开启了https，然后在机器人的配置文件中使用“`wss://127.0.0.1:6800/jsonrpc`"连接会报错”`cannot validate certificate for 127.0.0.1 because it doesn't contain any IP SANs`“
