Start in bugbug/tools/core/platforms/phabricator.py at _get_file_from_patch(), especially the client.get call around line 330, and trace how get_new_file reaches it. Reproduce or inspect the reported httpx.ConnectTimeout, then check nearby file-fetching paths for the intended error behavior. Done should include a verified resolution for this timeout case and a regression test if the existing test structure supports one.
