Subagent tasks silently cancelled on network interface change (Wi-Fi → Ethernet) #57538
Description
Description
Running background/foreground subagent tasks are cancelled when the machine's network interface changes (e.g., switching from Wi-Fi to Ethernet). The tasks show state cancelled with no error message, and there is no way to resume them — they must be relaunched from scratch.
A brief network interface transition should not tear down in-flight subagent sessions. Expected behavior: either the session survives the transition (reconnecting transparently), or it fails with a clear error explaining what happened and offering a way to resume, instead of silently cancelling.
This happened twice: two Task tool subagents (simple counting tasks) were launched in parallel; when the user switched from Wi-Fi to Ethernet mid-run, both were cancelled. Relaunching them afterwards (on the stable Ethernet connection) completed successfully.

Steps to reproduce
- Launch one or more subagent tasks via the
Tasktool (foreground or background). - While the subagents are still running, switch the machine's network connection from Wi-Fi to Ethernet (or any interface transition that briefly interrupts connectivity).
- Observe that the subagent sessions transition to
cancelledinstead of surviving the transition or reporting a resumable failure.

Thanks for the detailed report, @ciltocruz!
You're on OpenCode 1.18.35, which is v1. v1 now only gets fixes for critical bugs, such as data loss, security problems, or crashes and breakage with no workaround. Here the tasks can be relaunched and then complete, so this is unlikely to be fixed in v1.
We recommend upgrading to v2 (the
@opencode/clinpm package, which provides theopencodecommand). v2 has a separate implementation of tasks and subagents. These related v2 issues may interest you:If this also happens on v2, or you think it's more critical than it looks (for example, if work is lost that can't be recovered), please reply here with the details.

Fixed in v2

We haven't heard back, so I'm closing this as not planned. The report is about OpenCode v1 (1.18.35), which now only gets critical fixes, and relaunching the subagent tasks works around the problem. If subagent tasks also get cancelled when the network changes on v2 (
@opencode/cli), please open a new issue with your v2 version and the steps, or reply here. Thanks again for the clear report, @ciltocruz!
