In Google Chrome, the Internet traffic on some special Google websites alternates between UDP and TCP to improve browsing speed.
At the moment, BrowseControl can’t control the Internet from the UDP port.
1) Block QUIC by blocking UDP traffic
To fix this issue, our developers added an option to disable QUIC. This will block Internet traffic via UDP. This option is enabled by default under Tools > Client Settings > Internet Connection > Disable QUIC.
2) Windows Firewall must be ON
If your Windows Firewall is turned off, BrowseControl’s disable QUIC option cannot be integrated into the Firewall Settings. An inbound and outbound rule will be created on your client computer called “CW_QUIC”.
Make sure your Windows Firewall is turned ON and not disabled.
3) Configure your 3rd Party Firewall to block UDP (80 and 443)
Disabling QUIC option can only control the Windows Firewall settings. It cannot control any 3rd party firewall settings. If you manually installed an antivirus or a Firewall on your client computer, you will have to manually block UDP traffic to fix this issue.
Go to your Firewall settings and block UDP protocol on port 80 and 443.
