bug(opencode-go): All subscription models return "Request blocked by upstream provider"

[1335907208]

Description

Describe the bug

After logging in with opencode-go subscription, every model call uniformly throws error:
Request blocked by upstream provider.
No single model under opencode-go subscription can complete any chat/completion request.

Steps to reproduce

1. Install latest opencode release
2. Run opencode TUI, execute /login
3. Select opencode-go subscription auth flow, complete login normally
4. Switch any model under opencode-go provider
5. Send any prompt to trigger model inference
6. Error pops up immediately without any response content

Expected behavior

All subscribed opencode-go models should normally complete LLM inference requests without upstream block error.

Actual behavior

Every model request returns identical error message:
Request blocked by upstream provider.
No logs with detailed upstream status code, no retry logic takes effect.

Environment

• OS:
• OpenCode version: opencode --version
• Bun version: bun --version
• Network: Direct connection / proxy

Additional context

1. All models under opencode-go subscription are affected; no single model works.
2. No rate limit prompt, no API key expired reminder, only upstream block message.
3. Cleared local auth cache ~/.local/share/opencode and re-login multiple times, issue persists.
4. Other third-party API key providers (openai compatible) work fine, only opencode-go subscription auth is blocked upstream.
5. No custom modified config, default opencode.json with zero custom provider overrides.

Verification I've completed

• Searched existing open issues for identical Request blocked by upstream provider bug, no duplicate ticket found
• Cleared local auth storage and re-authenticated opencode-go subscription
• Tested multiple different opencode-go models to confirm full provider-wide block
• Confirmed network connectivity to other AI API providers works normally
• Did not use AI-generated bulk text, all descriptions written manually

This issue might be a duplicate of existing issues. Please check:

• Request blocked by upstream provider. #38216: Same "Request blocked by upstream provider" error affecting Go-tier models while free models work
• 401 AuthError: Request blocked by upstream provider #38195: Same "401 AuthError: Request blocked by upstream provider" error for opencode-go subscription models

Same issue here. All ocgo subscription models are returning "Request blocked by upstream provider" since yesterday. Models list can be fetched but none can do inference. Hope the team can fix this soon!
