Why do I see an error saying “weak ciphers are not accepted” when I try to use FTP?
If you use an old FTP program that doesn’t support modern versions of SSL encryption, you might see an error saying “cleartext sessions and weak ciphers are not accepted” when you try to connect.
This happens when you’ve turned on SSL encryption in your FTP program, but the program doesn’t know how to use modern, secure versions of SSL. It’s trying to use outdated and insecure (“weak”) encryption ciphers.
If you encounter this issue, you should upgrade your FTP program if possible. Using a version of the program that supports modern versions of SSL will fix it. If upgrading isn’t possible, you should turn off SSL encryption in your FTP program’s connection settings so that it makes a “plaintext” connection.
