推荐答案

可能会在您的网络策略上启用一些防火墙来阻止此请求。

在配置文件中尝试以下解决方案



< system.net>

< defaultproxy>

< proxy usesystemdefault =False

=proxyaddress =指定您的代理地址：指定端口号

bypassonlocal =False >

There Might be some firewall enabled on your network policy which is stopping this request.
try below solution in your config file

<system.net>
<defaultproxy>
<proxy usesystemdefault="False"
="" proxyaddress="Specify Your Proxy Address: Specify Port Number"
bypassonlocal="False">
