Dreamweaver SFTP Fail

[K T Cat]

Security on our servers was recently tightened and old, out-of-date encryption methods are no longer accepted. Unfortunately, these are the only ones Dreamweaver on my Win7 desktop seems to know for establishing an SFTP connection. On the Dreamweaver side, it just says it can't make a connection. On the server side in the error logs, I see this:

sshd[1770]: fatal: no matching mac found: client hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@openssh.com,hmac-sha1-96,hmac-md5-96 server hmac-sha2-256,hmac-sha2-512 [preauth]

Note that Dreamweaver was connecting to the servers just fine before we had to get rid of the old encryption methods, so I know all of the other settings are fine.

More details: I've got WinSCP on the same desktop machine which works just fine as does Putty. That means both of these have access to the updated encryption methods.

How can I get Dreamweaver to use the right one(s)?

Hi,

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?
