No Internet Connectivity Is Available after Closing Fiddler Everywhere
|Product Version||1.0.0 and above|
|Operating System||macOS, Windows, Linux|
By design, when the Fiddler Everywhere application is closed, it restores the default operating system proxy settings. However, on rare occasions, the application ends unexpectedly due to various reasons such as a software crash, OS interruption, hardware failure, and so on. In this case, how can I restore the default proxy settings and avoid losing the Internet connectivity?
To solve the issue, identify and remove leaked proxy settings so you can restore the lost Internet connectivity after Fiddler Everywhere stops unexpectedly.
In Fiddler Everywhere, disable the Live Traffic capturing, and close the application.
Go to the Start menu and type Proxy settings.
Go to Manual proxy setup and verify that the Fiddler proxy IP and Port are removed. By default, when your system is not using other proxies, the Use a proxy server is turned off with both the Address and Port fields empty.
Disable the Live Traffic capturing and exit the Fiddler Everywhere application.
On macOS, go to System Preferences > Network and select the active Internet adapter.
Go to Advanced... > Proxies.
Verify that the Fiddler proxy is not set for Web Proxy (HTTP) and Secure Web Proxy (HTTPS). If the Fiddler proxy is present, remove the IP and Port, uncheck both options (or restore your default proxy settings), and click Apply to apply the changes.
Click OK to confirm the changes.
In Fiddler Everywhere, disable the Live Traffic capturing and close the application.
On Ubuntu, go to Settings > Network.
Verify that the Network Proxy option is set to Off (or to your default proxy settings). If the Fiddler proxy is still present in the Manual proxy, remove it and disable the network proxy.
