Summary

On Windows, the QUIC client keeps retrying and never establishes a QUIC connection.
It prints Quic FAILED to connect followed by QUIC connection lost. exit, then restarts the client and repeats indefinitely.

Environment

  • OS: Windows <10> (run as Administrator)
  • Client version: 0.13 آلفا
  • Server: <Hetzner, ubuntu 22.04>

Steps to reproduce

  1. Install client on Windows.
  2. Configure server IP/Port/Key.
  3. Start the client.
  4. Observe the logs.

Expected behavior

Client should establish a QUIC session and keep the tunnel up.

Actual behavior

Client fails to connect and enters an infinite retry loop.

Logs / Evidence

Repeated output (from screenshot):

  • Attempting to connect to QUIC server...
  • UDP cleanup task running!
  • Quic FAILED to connect
  • QUIC connection lost. exit
  • close all tcp
  • close all udp
  • Connection close sent (code 0x0, reason )
  • Connectivity SystemExit!
  • cancelling error: - Retrying...
  • client is dead. restarting ...

Screenshot attached: (upload the screenshot)

Notes / Suspicions

This looks like UDP traffic not reaching the server (firewall/cloud firewall/ISP blocking UDP), or a mismatch in server address/port/key.
But I’m not sure what Connection close sent (code 0x0, reason ) indicates in your implementation.

با تشکر دوباره و هرگونه راهنمایی کمک کننده است.
