I'd like to help with this issue, but I need some clarification to ensure I understand the problem correctly. The diagnostic file shows an "OpenAI completion error: Connection error" when using deepseek-v3.2 via the openai provider, but I need a few more details:

1. What is your setup? Are you connecting to a self-hosted DeepSeek endpoint, a third-party proxy, or the official DeepSeek API using the OpenAI-compatible provider? What base URL have you configured?
2. What do you mean by "proxy based provider"? Are you referring to:
   • An HTTP/HTTPS proxy (e.g., corporate proxy, SOCKS proxy) that sits between Roo Code and the API endpoint?
   • An OpenAI-compatible API endpoint (like a local LLM server or API gateway)?
   • Something else?
3. Does this work outside of Roo Code? For example, can you successfully call the same endpoint using curl or another tool with the same credentials and base URL?
4. Have you configured any proxy settings in VS Code (http.proxy, http.proxyStrictSSL) or system-level environment variables (HTTP_PROXY, HTTPS_PROXY)?
5. Is this a regression? Did this previously work with an older version of Roo Code, or has it never worked for you?

Any additional details about your network setup and configuration would help narrow down the root cause.

Please tag @roomote in your response with the answers, and I'll be happy to investigate further and propose a fix.

Hi, I'm using agentrouter api end point, and also when I used new key, it worked fine. But I see some other issue while I'm changing the mode from code to architect. Will update you if it happens frequently. Thanks & Regards, Gaurav Gupta ***@***.*** +91-9945418006 http://about.me/gaurav.123337

Thanks for the update, @gaurav123337. Glad to hear the original connection error was resolved with a new API key.

Regarding the issue you see when switching modes (code to architect) -- I have been looking at the mode switching code and found a potential issue: if the provider profile activation fails during a mode switch (which could happen with proxy-based providers like agentrouter), the mode gets updated in state but the API configuration does not get properly switched. This could leave things in an inconsistent state.

I am working on a fix to add proper error handling around the profile activation during mode switches, so that even if profile loading fails, the mode switch completes gracefully and falls back to the current API configuration.

If you see the issue again, it would be very helpful to know:

1. What exactly happens (error message, UI behavior, etc.)
2. Whether you have different provider profiles configured for code vs architect modes
3. The diagnostic file output

I will open a PR with my attempt at a fix shortly.

[roomote-v0]

Opened PR #12099 with my attempt at addressing the mode-switching issue. The fix wraps the provider profile activation in error handling so that mode switches complete gracefully even if the profile activation fails (e.g. with proxy-based providers). Feedback welcome!
