Fix Windows 10 cannot automatically detect this network's proxy settings error
Windows has a built-in troubleshooting tool that can help you diagnose connection problems on your computer. When this tool detects a problem with your network, it automatically fixes it. Sometimes it points out the problem and recommends possible solutions. Other times, the network troubleshooter describes the problem without offering a solution.
A good example of the third case is the error message "Windows could not automatically detect this network's proxy settings." Of course, this message tells you that there is a problem with your network's proxy settings. What it doesn't reveal is how to fix the problem.
That's because proxy configuration issues are multifaceted and often tricky to troubleshoot, especially if you don't know where to look or what to do.
