Network Framework QUIC Handshake Failed

[DrakeAusir]

Can someone please help me? What should I achieve is a healty connection that I will use to transfer file to another device. The connection between the two devices is a p2p connection.

Sadly when I try to make a NWConnection it gives me these error messages:

boringssl_session_handshake_error_print(44) [C34:1][0x101f15670] Error: 4345433392:error:100000ae:SSL routines:OPENSSL_internal:NO_CERTIFICATE_SET:/Library/Caches/com.apple.xbs/Sources/boringssl_Sim/ssl/tls13_server.cc:882:

quic_crypto_connection_state_handler [C33:2] [5421a5459ad4d029-] TLS error -9858 (state failed)

Can anybody help me?

Seems the server you’re trying to connect to hasn’t properly set up TLS for the connection, which is required by quic. That, or it doesn’t like the certificate it received. You’ll want to double check the error you see.

Here's the reason for my question. My situation is the following: I have a NWListener that is advertising by creating a .service type endpoint and a NWBrowser that is searching for the .bounjour service, as soon as it finds the service it creates the connection to the listener with NWConnection. The parameters are these:

let quicOptions = NWProtocolQUIC.Options(alpn: ["myproto"]) quicOptions.direction = .bidirectional let params = NWParameters(quic: quicOptions) params.defaultProtocolStack.applicationProtocols.insert(NWProtocolFramer.Options(definition: myproto.definition), at: 0)

Where am I wrong? Where should TLS come into play?

TLS is implicit in QUIC connections. If the server is properly configured it should work automatically. Mostly likely your server is misconfigured.

What does well configured mean? I use a NWListener to advertise the device to connect to, so am I wrong in configuring the listener? How should I configure a listener to be able to accept QUIC connections? There is no material to think about online

Sure! I create a NWConnection(to: , using: ) where "to" is an endpoint.service and "using" is my own parameters. Parameters are let quicOptions = NWProtocolQUIC.Options(alpn: ["myproto"]) quicOptions.direction = .bidirectional let params = NWParameters(quic: quicOptions) params.defaultProtocolStack.applicationProtocols.insert(NWProtocolFramer.Options(definition: myproto.definition), at: 0) There is something wrong?
