   Thanks for the report! ECONNRESET has several possible causes, and a lot of reports came in this week, so we need a few details to work out which one you're hitting:

   1. Your OpenCode version (opencode --version, or the version shown in the desktop app), your Windows version, and how you installed OpenCode.
   2. The provider and model you're using (for example the built-in free OpenCode Zen models, OpenCode Go, or your own API key with a provider).
   3. VPN/proxy: does it fail with the VPN on, with it off, or both? Is HTTP_PROXY/HTTPS_PROXY set, or does the VPN route all traffic (TUN mode)? Roughly where in the world are you, and which ISP do you use?
   4. When it drops: you said the model starts answering and then the connection closes. Does that happen within seconds, or only on longer responses or tasks? Does a short prompt like hi work?
   5. Does it also happen in the plain TUI or with opencode run "hi", without the Telegram bot? (The Telegram integration looks like a third-party project, so it helps to rule it out.)
   6. Any logs from around the failure, if you can get them.

   You can reply here with the details or edit the issue. If you edit it, please also leave a short comment saying you've updated it, so we know you're done.

   These existing issues may be related, ordered from most to least likely. Please check whether one of them already covers your problem:

   • cli: hangs before sending request on networks that drop fragmented TLS ClientHello (post-quantum key share) #60399: ECONNRESET or hangs on some networks (mostly Russian ISPs, since Oct 29–30) because the TLS handshake is dropped; works with a VPN. In that case the connection fails before any response, though.
   • ECONNRESET: The socket connection was closed unexpectedly. For more information #59291: ECONNRESET that shows up mostly on complex or long-running tasks, after the model has been working for a while.
   • Desktop 2.1.4 on Windows: ECONNRESET without VPN, works with VPN, curl succeeds #60533 / ECONNRESET on built-in Zen provider — works with VPN, fails without (same network, no rate-limit JSON) #60422: Windows, ECONNRESET without a VPN, works with one (being handled as duplicates of cli: hangs before sending request on networks that drop fragmented TLS ClientHello (post-quantum key share) #60399).
   • ECONNRESET: The socket connection was closed unexpectedly. For more information, pass verbose: true in the second argument to fetch() #60620: ECONNRESET both with and without a VPN, from Russia.

   We haven't heard back, so I'm closing this issue for now. We still needed your OpenCode version, the provider and model, whether it fails with the VPN/proxy on, off or both, and whether it also happens without the Telegram bot. Without those we can't tell which cause of ECONNRESET you're hitting.

   If the connection fails before any response, on a network where a VPN makes it work, #60399 most likely covers it. You can follow that issue instead.

   If it still happens and it's a different problem, please reply here with those details or open a new issue, and we'll take another look. Thanks!
