No response

Start by reproducing the VLESS + Reality + Vision connection on Debian 12 with DAE v1.1.0 and the supplied configuration, then inspect the change introduced after PR #1388. Trace the source of the "nil ecdheKey" warning and compare behavior with PR #1388 or an earlier working version. Done means the connection succeeds without that error.
