Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
When connecting to the remote host over SSH, DNS resolution failed, preventing the Cursor Server from being downloaded; subsequently, the installer package uploaded from the local machine was corrupted during decoding/extraction (tar/gzip failure), causing the Cursor remote server installation to fail and interrupting the SSH connection preparation phase. It worked prior to the update around Aug 25, and the issue appeared after that update.
