Everytime I sucessfully login to a remote server using ssh, the zsh terminal would stuck unless I do a Ctrl+C. There’s no problem with the ssh login, and I can even run python scripts in vscode. So not a problem with ssh login? It also requires three Ctrl+C after I type exit for it to really exit the ssh connection everytime.

Things I’ve tried:

1. The same happens when opening a new terminal in vscode. But source ~/.zshrc works just fine after I bring back the terminal by Ctrl+C.
2. I also tried to comment out all the contents in zshrc and try to re-connect in my local terminal or launch a new terminal in VS Code, and the problem persists (So not a problem with zshrc?).
3. I tried uninstalling vscode from the server, removing the ~/.vscode-server folder, and using my local machine’s terminal to connect. The problem persists (So not a problem with VS Code?)
4. I also tried this answer, but the date returns the correct time.
5. Tried to use -vvv option in ssh to see the verbose ssh login info, but there’s nothing else after “Last login” information where the terminal is stuck.
6. Tried to add set -x in zshrc to see the verbose zshrc execution info, but there’s no output as I commented everything in zshrc.

I’m in desperate need of any suggestions that might help solving this issue! Appreciate it!
