[bug] Country, region, or territory not supported error

[justcarlson]

Summary

Opencode session fails with Country, region, or territory not supported while running an explore task, resulting in a streamed AI_APICallError.

Version

opencode v1.1.19

Steps to Reproduce

1. Start a session in Opencode.
2. Run an explore task (e.g., "Explore templater config") that triggers tool calls.
3. Observe the stream error.

Expected

The task runs or returns a recoverable error without blocking the session.

Actual

Session stream errors with a 403 and unsupported_country_region_territory.

This has basically made Opencode unusable, unfortunately.

Interesting. This doesn't appear to affect Big Pickle. Might just be affecting OpenAI models in Zen.

+1

fwiw Sonnet 4.5 thru Zen (Black sub) gives me

Forbidden: {
  "error": {
    "type": "forbidden",
    "message": "Request not allowed"
  }
}

immediately.

5.2-codex sometimes does a bit of thinking before returning country unsupported.

gemini-3-pro seems to work

@justcarlson @irth i'm also having issues w/ gpt and claude models.. so far we know it's impacting some part of Canada. where are you guys physically?

From Australia here, just started getting hit by this too. I'm using OpenCode Zen as well. No crazy setup, just my laptop and an API key to Zen.

[fwang]

can y'all give it a try and see if it's fixed?

^ upstream network routing issue.. just rolled out a workaround

tried sonnet, seems to work
opus at first was sending messages that were like,

Now

Now I have 

Now I have a clear

picture, which

very slowly, one by one, (I reverted and switched to sonnet, maybe it's in logs but I don't wanna mess with the session as I moved on), but I cannot reproduce this behaviour now and it also seems to work for me

I am in the Northeast USA, not behind a proxy, so I should be connected (I hope) to US-East.

Alright! Looks like it's fixed! Tool calls with opencode/gpt-5.2-codex are now successful.
