Unable to Establish QUIC Connection: Check Failure in QuicCryptoClientConfig

Hello everyone,

We attempted to build and run quic_client (from master) but encountered a problem when trying to connect it to a server within the quic::QuicCryptoClientConfig::QuicCryptoClientConfig() function.

Here is the error message along with the call stack:
WARNING: All log messages before absl::InitializeLog() is called are written to STDERR

We executed ./quic_client on Ubuntu 22.04 and encountered failures when connecting to every server we tried.

Does anyone know how to solve this problem, or am I missing something?

Thank you for your assistance.
