Qlik Sense slow to load with error ERR_QUIC_PROTOCOL_ERROR displayed in the browser devtools

[Damien_Villaret]

Qlik Sense is slow to load with error ERR_QUIC_PROTOCOL_ERROR displayed in the browser developer tools.

Resolution

Disable the QUIC protocol in your browser.

Examples:

Google Chrome
Edge

Cause

The QUIC protocol is a newer protocol that aims to speed up loading speed, however some network devices do not support it and it will have the opposite effect of making things slower when the connection is going through those devices.

Environment

Qlik Sense Enterprise on Windows
