Cloudflare takes 5 mins sometimes to properly establish the connection.

Sometimes, doing "factory reset runtime" and try again works. Do you get any reply with ping command like ping your-random-server-address.trycloudflare.com? If you got reply, probably argo tunnel is working and maybe some ssh client settings need to be fixed. If you don't get any reply, maybe argo tunnel take long time to become accessible or cloudflare is not providing their service in your region.

it seems to be working fine right now. I believe it was something temporary
