Network error occurred. Check your internet connection.

Error message

Network error occurred. Check your internet connection.

What it means

dsk_deepseek catches dsk's NetworkError and re-raises it with a fixed message telling the developer to check their internet connection. It means a socket/DNS/timeout-level failure occurred while talking to the free DeepSeek endpoint, before any API-level response was received.

Solutions

1. Verify general connectivity (curl https://chat.deepseek.com) and DNS resolution
2. Check proxy/VPN/firewall settings and required HTTPS_PROXY env vars
3. Retry with backoff — transient network blips during streaming are common
4. Fall back to another provider backend (litellm_fn, etc.) in config.ini

When it happens

Trigger: Calling LLMProvider.dsk_deepseek(history) when the underlying dsk API raises NetworkError during session creation or streaming chat_completion — DNS failure, connection refused/reset, TLS error, or read timeout.

Common situations: Offline machine or flaky Wi-Fi; corporate proxy/firewall blocking chat.deepseek.com; DNS misconfiguration; long streaming responses exceeding timeouts on unstable connections.
