@Migueldeicaza I appreciate the write up! This does not work on my Synology host - the connection is insta-dropped whenever I navigate away from La Terminal. Can I help diagnose? It’s pretty frustrating!
@smeger I believe synology was lacking a way to upload the agent. In this case, you can try “tmux” for session preservation
