proxy server is not responding

How to fix "Proxy server isn't responding" error!

- Disable the Automatic Cacheing of a Proxy.

- Disable the Automatic Proxy Result Cache by using the following registry key:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings

Value: EnableAutoproxyResultCacheType: REG_DWORDData value: 0 = disable caching; 1 (or key not present) = enable automatic proxy caching (this is the default behavior)

If the registry key is not present, you can create the registry key by using the following registry file:
Windows Registry Editor Version 5.00[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings]"EnableAutoProxyResultCache"=dword:00000000"

- Open RUN, Type regedit and click OK.

- in registry, browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings

- change "ProxyEnable" value from 1 to 0

- delete the entry "ProxyOverride"

- delete the entry "ProxyServer"

- browse to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings

- change "ProxyEnable" value from 1 to 0

- delete the entry "ProxyOverride"

- delete the entry "ProxyServer"

- browse to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\NlaSvc\Parameters\Internet\ManualProxies

- in "Default", deleted the listing "http=127.0.0.1:56124;https=127.0.0.1:56124"  so it would be blank (or value not set)

- browse to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\NlaSvc\Parameters\Internet\ManualProxies -

- in "Default", deleted the listing "http=127.0.0.1:56124;https=127.0.0.1:56124"  so it would be blank (or value not set)

- browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections

- delete the key "DefaultConnectionSettings"

- delete the key "SavedLegacySettings"

- both of these keys had the proxy and loopback information embededed in their value data, which would not show up for a registry search for "127.0.0.1"

Hope that helps. Good luck.
