OpenHands [Bug]: timeout during MCP stdio fetch

Is there an existing issue for the same bug? (If one exists, thumbs up or comment on the issue instead).

[x] I have checked the existing issues.

Describe the bug and reproduction steps

I am running in docker headless mode behind a proxy. I am not able to get the agent alive as there's timeout happening during the micro agent activation at runtime. `05:34:52 - openhands:DEBUG: action_execution_client.py:370 - [runtime 6faf08acdbc246c4bf43d3fa3ebb0c7e] Updating MCP server to: [{'name': 'fetch', 'command': 'uvx', 'args': ['mcp-server-fetch'], 'env': {}}] 05:35:02 - openhands:INFO: agent_session.py:194 - Agent session start 05:35:02 - openhands:ERROR: session.py:201 - Error creating agent_session: timed out Traceback (most recent call last): File "/app/.venv/lib/python3.12/site-packages/httpx/_transports/default.py", line 101, in map_httpcore_exceptions yield File "/app/.venv/lib/python3.12/site-packages/httpx/_transports/default.py", line 250, in handle_request resp = self._pool.handle_request(req) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/connection_pool.py", line 256, in handle_request raise exc from None File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/connection_pool.py", line 236, in handle_request response = connection.handle_request( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/connection.py", line 103, in handle_request return self._connection.handle_request(request) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/http11.py", line 136, in handle_request raise exc File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/http11.py", line 106, in handle_request ) = self._receive_response_headers(**kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/http11.py", line 177, in _receive_response_headers event = self._receive_event(timeout=timeout) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_sync/http11.py", line 217, in _receive_event data = self._network_stream.read( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/httpcore/_backends/sync.py", line 126, in read with map_exceptions(exc_map): File "/usr/local/lib/python3.12/contextlib.py", line 158, in exit self.gen.throw(value) File "/app/.venv/lib/python3.12/site-packages/httpcore/_exceptions.py", line 14, in map_exceptions raise to_exc(exc) from exc httpcore.ReadTimeout: timed out

The above exception was the direct cause of the following exception:
