I was a user of ForkLift FTP v3.58 but that app stopped working on Sonoma and the company will not update it, because I suppose, they want to push you to buy their upgrade.
I tried to connect to my servers (two different servers on two different hosting companies). ForkLift did not work on Sonoma.
Then I tried CyberDuck. It works fine.
Not even trying FTP or SFTP through terminal works on Sonoma.
So, it is a Sonoma problem.
