    Hello, I have a problem with internet access on the CHROME browser, windows 7.
    There is a message saying: ERR_PROXY_CONNECTION_FAILED '
    Following this lead I should simply uncheck the use of a proxy server and it should work. That's the problem here. After enabling "Change proxy settings ..." the "LAN settings" button is not illuminated and as a result I cannot uncheck it but what is important in this field is the annotation "Some settings are managed by the system administrator".

    The network diagnostic tool says:
    Troubleshooting completed successfully. Problems found: The remote device or resource does not accept the connection.
    Detailed information: The device or resource configuration (www.google.com) does not accept connections using the World Wide Web (HTTP) service port.

    After entering In CMD: ipconfig / all you can see:

    I think there is no problem here. I entered DNS and other things manually without results. The firewall does not block this either.

    Fun fact from IE: The proxy server is not responding. Check the proxy server settings. 127.0.0.1:8080.


    What works? Firefox is working properly after disabling proxies, pinging properly in cmd. Internet via Wi-Fi has a connection. Dropbox updates files.

    Scans from the FRST program are attached.

    I also found a command in this forum that checks the entered proxy server in CMD, the answer was that there is no proxy server set.

    AdwCleaner 7 found two problems: PUP.Optional.Legacy and PUP.Optional.Prxy.SvrRST. There are no changes after deleting them.

    Please help. best regards
