Hi, I guess it's because of version mismatch. Our master branch has not supported the final versions (0x00000001 and h3). If your client only supports the final versions, it's incompatible with ATS master.
Maybe you can try our 10-Dev branch. The branch has support for the final versions. I added the support when we switched to using quiche as QUIC implementation and I haven't built ATS with openssl since then, so I'm not sure if it really works with openssl now.
