Generic "connection error" -- Debug steps? #6991
Description
App Version
3.25.11 & 0.0.6534
API Provider
OpenAI Compatible
Model Used
gpt-oss-12b, llama-4-maverick, llama-3.3-70b
Roo Code Task Links (Optional)
No response
🔁 Steps to Reproduce
- Fresh VSCode profile, install only Roo Code (or nightly) and Network Logger
- Open Roo Code
- Edit default API configuration
- Select OpenAI Compatible
- Enter endpoint (verified correct)
- Enter API key (verified correct)
- (Models populate)
- Select model (tried all 3 listed above)
- Save
- Done
- Send "hello" in chat
- Generic "Connection error." message:
💥 Outcome Summary
Network Logger does NOT show a request to the /models endpoint, but the models populate and I can see the request in the server logs.
Network Logger DOES show a request to the /api/chat/completions endpoint, which does NOT show up in the server logs.
Same endpoint/key/models work in Cline.
I'm using an ssh-based socks5 proxy via a PAC file, launching VSCode with --proxy-pac-url=http://localhost:8000/socks5-ssh.pac
Cline works fully and Roo's model discovery works so I believe this part is fine unless the actual chat completions calls use a different fetch method than the models discovery which doesn't respect VSCode's patched fetch which respects the PAC proxy file? I've also tried setting the proxy in VSCode's http.proxy settings, but this doesn't seem to change anything.
How can I debug this further? Is there a debug setting or etc I can turn on to get more info?
I collected a .har file for the network activity, but Github doesn't allow it as an attachment
