My guess is that the SSH traffic is being routed toward the connection refused computer and the connection refused computer needs its firewall configured to allow incoming SSH.
I'd check your network routing to ensure SSH traffic is permitted to go to both machines, and to make sure you have no rules redirecting all traffic on that port to one machine. Also, check each machine's network settings to ensure incoming SSH is permitted. The only issue I can imagine after that is user authentication to each machine, so make sure you use the full user@hostname address when specifying users, especially when two machines have users with the same name Thanks | おおきに / ありがとう | Kiitos | Merci | Gracias | Obrigada | Grazie | 谢谢 | Danke | Wado | спасибо, 賢進ジェンナ「Kenshin, Jenna」 "You should be as alive as you can until you're totally dead!" - Dylan Moran 2025年12月10日 11:12 差出人: [email protected]: > On Wed, 10 Dec 2025, Ben Koenig wrote: > >> If this were a key or authorization issue you would get a different error. >> Connection refused is networking related.
