Disable "Experimental QUIC protocol" flag

The purpose of the QUIC protocol is to improve transport performance over TCP for internet traffic. QUIC utilizes UDP ports 80 and 443, and in some cases, UTM (i.e., Unified Threat Management) features may not be able to function correctly, such as the web filtering specifically on Google Chrome if the clients bypass any transparent proxies. Nevertheless, other browsers like Internet Explorer and Mozilla Firefox, for example, might not have these problems. 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.
2. Search the Experimental QUIC protocol.
3. Change "Default" to "Disabled" option from the drop-down menu.
4. Restart Google Chrome for your changes to take effect.

Changing maximum allowed TLS version

The server that presents the website may be an old version of TLS which is one of the possible reasons for the problem to arise. Transport Security Layer (TLS) is a cryptographic protocol used for creating unspoiled transmission of information across networks of computers. Currently, the version that is wildly distributed is TLS 1.2 and TLS 1.3 is already available as the final version while offering enhanced security improvements. Old TLS version may as well lead to necessary software update and, in turn, the error might be also situationally generated in the browser. Enabling the TLS version on web server to the latest stable version (TLS 1.2 or TLS 1.3) is recommended, so that there are no errors of communication, while dealing with remote devices like browsers.

1. Open chrome and type chrome://flags/ in the address bar.
2. Search Maximum TLS version enabled.
3. Select the version 1.3 which is set to Default before.
4. Restart Google Chrome for your changes to take effect.
