Hey, We've found a server that is intolerant of our offer to use delegated credentials. This seems to run a modern nginx and TLS 1.3, but it is not producing the same handshake keys as us, so I can't tell if it supports the extension or not (as the EncryptedExtensions message is indecipherable). The TLS stack is unknown, but as it supports ARIA, CAMELLIA, and CCM_8 (!) that might narrow things down a little. Is anyone deploying delegated credentials that I'm not aware of? Or has the codepoint assignment (34) run afoul of an experiment we're not aware of?
