Why is this error appearing in chrome load resource: net::ERR_QUIC_PROTOCOL_ERROR
The error appears to occur when the QUIC protocol is blocked (e.g. by an ISP) along the route between you and the target site. As a workaround, to this error, you can disable QUIC in Chrome by disabling the enable-quic setting by navigating to:
chrome://flags/#enable-quic
And changing the Experimental QUIC Protocol drop down to Disabled.
QUIC (Quick UDP Internet Connections) is a next generation transport over UDP, which aims to reduce latency (goal: 0-RTT connectivity overhead), deliver better multiplexing, introduce packet pacing, error correction, and more.
