Hi All,

I am trying HTTP3 on the released 7.84.0 build with the latest ngtctp2/nghttp3 libraries and I can't make QUIC connection.
For test I just used url: https://curl.se/ which is hosted in nginx with quic support.

My setup (Win32 build) is
libcurl 7.84.0, openssl+quic 1.1.1m, ngtcp2 0.6.0, nghttp3 0.5.0

Everything was OK in 7.83.1 with ngtcp2 0.5.0, nghttp3 0.4.0

The sever returns
    CONNECTION_CLOSE (Transport) Error code: FRAME_ENCODING_ERROR
        Frame Type: CONNECTION_CLOSE (Transport) (0x000000000000001c)
        Error code: FRAME_ENCODING_ERROR (7)
        Frame Type: 9077
        Reason phrase Length: 0
        Reason phrase:

My client seems to send bad Tls data, which Wireshark marks as "Unknown" parts.
Some of that "Unknown" parts contain ALPN stuff:

Here is the Initial QUIC packet info:

Has anybody stepped on this issue and if there is an easy way to fix it?

Thanks,
