TLS1.2 support is not enabled.
Dreamweaver doesn't support TLS 1.2, but almost every server I work with these days requires it- and the rest will shortly. This makes the Dreamweaver site management and FTP transfers useless at this point. Why would you ignore for years this common issue and not support a common technology!
Dreamweaver 18.2 is live. It can be downloaded from creative cloud Desktop application.
It includes the SFTP connection issue fix.
Try connecting to SFTP server with this build. Looking forward to your feedback!

Can you tell us the hosting server provider that you are trying to connect to?
Also, if you could mention the list of ciphers, MACs and KexAlgorithms that the server supports- this will help us in debug the issue better?
We do support TLS 1.2, but we have one known issue with supporting one of the hosting providers which has moved to a newer MAC(Message Authentication Code Algorithm) which are not compliant with Dw. The Dw team is working on adding support for additional MAC that can help support connecting to this hosting provider as well.
We would request you to share the following details so that we can debug this and confirm the issue-
1.Can you tell us to which hosting server are you trying to connect?
2. Please mention the ciphers, MACs and KexAlgorithms which are supported by your hosting server.
