Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• wlt.ustc.edu.cn
  • Triggering command: /home/REDACTED/work/wangluotong/wangluotong/.venv/bin/python3 /home/REDACTED/work/wangluotong/wangluotong/.venv/bin/wangluotong (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
