Disable "Experimental QUIC protocol" flag

The QUIC protocol aims to offer improved transport performance compared to TCP for internet connections. QUIC utilizes UDP ports 80 and 443 and, in some cases, allows clients to bypass transparent proxies, potentially causing issues with certain UTM (Unified Threat Management) features, such as web filtering, specifically on Google Chrome. Other browsers like Internet Explorer or Mozilla Firefox may not encounter these issues. To disable the QUIC protocol in the Google Chrome internet browser, follow these steps:


  1. Open chrome and type chrome://flags/ in the address bar.

The latest widely used version is TLS 1.2, while TLS 1.3 has been released as a final version and offers enhanced security features. Therefore, if the web server is using an older TLS version, it may result in compatibility problems and potentially trigger the error in the browser. Updating the TLS version on the web server to the latest stable release (TLS 1.2 or TLS 1.3) is recommended to ensure secure and error-free communication with modern browsers.
