SFTP works on one Mac, but not another

I have a rule to follow a folder called "transcripts" and if any HTML files land in it, upload them to my server. I created the rule on my MacBook Air and it works. but the same rule, synced through iCloud to my MacBook Pro does not work. I'm accessing my RSA key on both, the ports are the same, the protocol is the same, the user name is the same, and the start path is the same.
The one thing that's different is on the working Mac, it also shows dots for an entered password. If I copy my server password from 1Password and paste it into the password field in Hazel on the non-working Mac and try to connect, it says:
Paul studied my log files (quite a while back) and wasn't able to figure out what's wrong. I figured it was worth posting here to see if anyone else had an idea.
