'charles proxy internet connection

I am trying to collect log for Android mobile device through charles proxy. As soon as I connect my device charles proxy Application, I lose the internet connection on my mobile device and mac internet connection.

Steps followed: 1. Open charles proxy 2. Click on Proxy tab> Proxy settings 3. Made sure, port is 8888 4. Go to help (charles proxy app) and click on local IP 5. Connect the mobile device to same wifi 6. Long press on wifi and click on modify network 7. click on advance settings 8. choose proxy as "manual" 9. Enter proxy host name as "IP address from step 4 (local host ip address)" 10. Enter Proxy port as "8888" 11. Click on connect

As soon as complete step 11, I lose my internet connection on the mobile device and mac. Though I can see the device's logs in charles proxy.

If I open the browser it gives the below error:

On mobile device: "This site cannot be reached. www. google.com unexpectedly closed the connection"

on the web (mac machine) error message is: "This site can’t be reached www.google.com unexpectedly closed the connection. Try: Checking the connection Checking the proxy and the firewall Running Network Diagnostics ERR_CONNECTION_CLOSED"

Note: I have tried on windows 10 laptop too. Same issue. As soon as I close the charles proxy, the internet connection comes back.

By default, all hosts are whitelisted. If you whitelist one particuliar host (eg. right-click on it in the log and click "White List"), this default behaviour will not longer be applied and you will have to decide for each host whether you wish to whitelist them or not. A solution to your problem would be to go to the "Tools" menu > "White List" and change the "Blocking action" rule to something else than "Drop connection". Charles Proxy White List Settings

I selected "Tools" menu > "White List". Uncheck "Enable White List". This way all are whitelisted and not just the ones from Locations mentioned.

One more way would be to leave "Enable White List" checked, but Add an entry for both http and https protocols. Type * in host and save the changes. This way all locations will pass through.

Make sure that the option Allow list isn't checked. From my understanding, Charles works by allowing lists only, which is why the browser doesn't work well.
