net::ERR_QUIC_PROTOCOL_ERROR.QUIC_PACKET_WRITE_ERROR

[Tony Zhen]

Hi All

Is there anybody knows how to fix below error? 

I meet below error when try to connect to quic server as below.

 const transport = new QuicTransport(url);

I don't know why there is always below error.

Failed to establish a connection to quic-transport://rwgdev50106.xxxdev.us:8801/: net::ERR_QUIC_PROTOCOL_ERROR.QUIC_PACKET_WRITE_ERROR (Write failed with error: -142 (Unknown error)).

I start up chrome like this:

chrome.exe --enable-experimental-web-platform-features --enable-quic --quic-version=h3-27 --origin-to-force-quic-on=rwgdev50106.xxxdev.us

My chrome version is: 

85.0.4166.0 canary （64 bits）  

Best regards,

Tony Zhen

I found that this error happens only when I try to connect to quic server via VPN.

Hi,

> I found that this error happens only when I try to connect to quic server via VPN.

Does this mean the VPN system blocks QUIC?

-142 is MSG_TOO_BIG. I suspect the issue here is that the CPN has an MTU that is too small. What MTU does this VPN have?
