Proxy error with using borwser after installing ABP app

[mystvearn]

Hi,

I have installed and removed the ABP app as mentioned on my Galayx Note 3, however, my browser, chrome and google play does not work on mobile data. It does work on Wifi.

Whenever I open the browser it says: "Unable to connect to proxy server"
Error code: ERR_PROXY_CONNECTION_FAILED

I have no proxy server apps. The only app I think is ABP which has proxy. How do I fix this back to normal?

Thank you

If ABP is no longer installed, make sure that your proxy settings are set to not use a proxy, rather than to use localhost at port 2020.

you have to install adblock again and disable it from the app. uninstalling app wont remove the proxy settings.
I use adaway but the concept is the same
