BMP using chainedProxy failed with network error "ERR_EMPTY_RESPONSE"

[lindaxuxlj]

It is under VPN network so I use API setChainedProxy to set upstream proxy . This method has been worked well before. But now failed with proxy error "ERR_EMPTY_RESPONSE". Could u check where is wrong with this API ? The proxy server isn’t responding • Check your proxy settings xx.xx.xx.xx:55060. Go to Tools > Internet Options > Connections. If you are on a LAN, click “LAN settings”. • Make sure your firewall settings aren’t blocking your web access. Ask your system administrator for help.
