Title
Configure system-wide web proxy for .NET web applications -
Description
User has a proxy server configured on the Rapid Recovery core server and has already configured proxy settings according to KB157668, but the core is still unable to contact the license portal through the proxy. -
Cause
Rapid Recovery does not support proxies. It relies on .NET Framework to establish an internet connection. Depending on the proxy type and environmental configurations, .NET Framework may require a special configuration so it can connect to the internet using the proxy. -
Resolution
1. Stop the core service2. Open notepad as Administrator2.1 Open C:\Windows\Microsoft.NET\framework\v4.0.30319\config\machine.config and Search for <system.net>.If it does exist, edit this section as appropriate. If it does not exist, add the following text as the second line from the end (</configuration>) and substitute the proxy address as appropriate for the environment:
<system.net><defaultProxy><proxy autoDetect="false" bypassonlocal="true" proxyaddress="http://proxy:8080" /></defaultProxy></system.net>2.2 Save the file
2.3 Apply the above changes on the following three files
- C:\Windows\Microsoft.NET\framework\v4.0.30319\config\web.config
- C:\Windows\Microsoft.NET\framework64\v4.0.30319\config\machine.config
- C:\Windows\Microsoft.NET\framework64\v4.0.30319\config\web.config
3. Open an elevated command prompt and run the following command, replacing the proxy address:
netsh.exe winhttp set proxy http://proxy:8080 bypass-list="*.example.com"Note: The bypass-list argument is optional4. Verify the proxy setting
netsh.exe winhttp show proxy5. Optionally a bypass list can also be added to .NET FrameworkExample for bypassing 10.*.*.* , *.domain.int and *.example.com
<system.net><defaultProxy><proxy autoDetect="false" bypassonlocal="true" proxyaddress="http://proxy:8080" /><bypasslist><add address="10\.\d{1,3}\.\d{1,3}\.\d{1,3}" /><add address="[0-9a-zA-Z]+\.example\.com$" /><add address="[0-9a-zA-Z]+\.domain\.int$" /></bypasslist></defaultProxy></system.net>6. Reboot server
