Hi ​@세은 김, 

I hope it’s OK to reply in English.

I understand you’re seeing “Connection error: -106” which is preventing you from opening your file.

This error typically indicates a network setting that’s blocking Figma from connecting to required resources — most often a firewall, proxy, or VPN.

Please try the steps below to help resolve the issue:

1. Try a different network (another Wi-Fi or a mobile hotspot). This helps determine whether the issue is specific to your network. Please check: Adjust your network settings

2. Does this happen in the browser, the desktop app, or both?
   If you’re using the Figma desktop app on a work-managed computer, ask your IT team whether any network settings are blocking Port 443. See: Connection or server error 403

3. Disable extensions (especially ad blockers) temporarily, as they can interfere with connections.

4. Flush your DNS and restart your browser 

5. Clear the Figma desktop app cache (and your browser cache). Instructions: Clear the Figma desktop app cache

If you’ve tried all of the above and still see the error, I’ll send you a DM shortly with next steps so we can investigate further.

Thanks,
