Hello, I am trying to connect via sftp over ssh to test this program to see if I can use it for a small business. I am entering all the correct data for an sftp connection, but am receiving the following error:

any help on rectifying this issue would be wonderful, as if I can make this work, I will be purchasing a license to use this software long-term.

Manually enable the insecure AES CBC ciphers in the SSH dialog in the favorite properties.
