Cyberduck SFTP Connection failures on Mojave
I am getting repeated "Connection failed" errors in Cyberduck 7.3.1 on my iMac running Mojave. Since I'm having the same problem with two different hosting companies (Flywheel and Go Daddy) I've been focusing on the Cyberduck app as the issue. I know I have the correct settings and info entered in CD, and SSH enabled with both hosts.
In my efforts to resolve this, I've tried:
Changing password at each host
Deleting known_host files
Uninstalling and downloading a clean copy of CD purchased from the App store
Checking "Remote login" in System Preferences/Sharing
What else might try, short of trying a different FTP client? I'm willing to do that if i can't resolve CD but would prefer to keep using CD -- I've had it for a long time and it has worked welll up until a few days ago. What did I change at that time? Nothing... it just stopped connecting.
Help appreciated, TIA
