OpenCode Go hangs forever after "build" on Windows (v1.17.13)

[luis-hsl]

Description

Environment:

• Windows 11
• OpenCode CLI 1.17.13
• OpenCode Go subscription purchased today

Problem:
Every request hangs indefinitely after:

build · glm-5.2

The same happens with:

• opencode-go/glm-5.2
• opencode-go/qwen3.6-plus
• opencode-go/deepseek-v4-flash

What I verified:

• Authentication succeeds.
• opencode models lists all OpenCode Go models.
• opencode providers list shows "OpenCode Go api".
• curl https://api.opencode.ai returns HTTP 200.
• Internet connection is working.
• Reinstalled the CLI.
• Rebooted the PC.
• Logged in again.

Logs stop at:

llm.runtime=ai-sdk
llm.provider=opencode-go
llm.model=glm-5.2

No error is printed after that.

Additionally, opencode web eventually shows browser errors like:

ERR_CONNECTION_REFUSED
ERR_CONNECTION_RESET

Any ideas on how to debug this further?

I'm experiencing exactly the same issue on Windows.

Environment:

• Windows 11
• OpenCode CLI 1.17.13
• OpenCode Go subscription (purchased today)

Reproduced with:

• opencode-go/glm-5.2
• opencode-go/qwen3.6-plus
• opencode-go/deepseek-v4-flash

The CLI always hangs after:

build ·

It never returns any tokens or errors.

Things I've verified:

• Authentication succeeds.
• opencode models lists all OpenCode Go models.
• opencode providers list shows OpenCode Go api.
• curl https://api.opencode.ai returns HTTP 200.
• Reinstalled OpenCode.
• Logged out and back in.
• Rebooted Windows.
• No plugins enabled.

opencode run, the TUI, and opencode web all exhibit the same behavior.

Happy to provide additional logs if needed.

Additional debug:

When disabling thinking or running agent mode explicitly:

opencode run --model opencode-go/deepseek-v4-flash --thinking=false "test"

returns:

UnknownError:
Unexpected server error
