Hi Everybody,

Since the update on DW18, my saved connections via SFTP dont work anymore. FTP still works.

Error says

An FTP error occurred - cannot make connection to host. Your login or password is incorrect

It worked before the update and it still works with Filezilla with the same settings ...

Does anybody have an idea?

Iris

Hi TODD-B8S​,

CAn you please share more details on this.

What error you are seeing , any snapshot or gif would help.

Also, it would be great if you could share below info with us. It will help in debugging us better:

  • Hosting provider used
  • List of ciphers, Mac's, Kex algorithms.
  • Are you able to connect to other clients say filezilla, putty.
  • In Dreamweaver, what is your connection mechanism.., is it username/password or through identity file.
  • If identity file, make sure you rae using .pem and not .ppk file.

Looking forward to your reply!

Regards,

Mahak,

I'm attaching a couple a screencaps showing the error that I'm receiving when trying to connect to my hosting provider.  I've contacted them concerning the ciphers, Mac's, and Kex algorithms and will reply with that info once I receive a response.  To answer your other inquiries:

Cart32.com = hosting provider

I am able to connect fine using the current version of Filezilla.

DW connection mech is user/pass

This error is generated when trying to connect from within DW itself.

This error is generated when clicking the "Test" button within the Manage Sites dialog box.

I have verified that the username and password are correct.  Like I stated above, I can connect fine and update the website with Filezilla.  Thank you for your assistance.

Same here, we can't connect with our servers on DomainFactory. 'cause DW2018 still do not support the modern security requirements.  Annoying (and not the only problem with DW2018 ...)

but the webdav connection is secure and working fine with dreamweaver cc 18.0 and domainfactory. the only handicap is the slower speed...

"I guess the reason is, that our german hoster domain Factory has updated their SSH-Ciphers.

RSA/DSA Keys smaller than 1024 bit are no longer supported due to security reasons. The hosters support suggests to change our software infrastructure..."

It is exactly like that. domainFACTORY wrote that Adobe needs to update the Dreamweaver CC 18.0.

For me, SFTP works with Filezilla and WebDAV with Dreamweaver on my domainFACTORY website.

Hi,

ssh_hosts file is created once Dw connects to sftp server but in your case Dw18 hasn't connected even once so that file would not be created. It is actually a way to remember the connection credentials locally on your computer so that you don't have to enter the credentials again and again in DW.

Coming to the issue that you are facing, we have SSH-2.0-OpenSSH_4.6 supported in Dreamweaver which has a super set of ciphers/key exchange algorithms allowed from what you mentioned now your server supports.

For instance, I tried connecting Dw18 via SFTP  to one of my servers and the following were used in the connection-

Kex: 'diffie-hellman-group-exchange-sha256' Host Key: 'ssh-rsa' C2S : 'aes128-cbc, hmac-md5, none' S2C : 'aes128-cbc, hmac-md5, none'

As you can notice that client to server and server to client have these in common- aes128-cbc and hmac-md5 but if I check the list in your server details, these algorithms are not there now.

So, I am not sure but we might have to upgrade our Open SSH version in order to support connection to your server now- and that is a story we can prioritize.

In the meanwhile you could try other resolutions posted on this thread and let us know if it works.

I knew this post, but there is no ssh_hosts file in the corresponding Dreamweaver 2018 CC folder on Win 10 (~\AppData\Roaming\Adobe\Dreamweaver CC 2018\de_DE\Configuration)

Hi Iris & Adobe Staff,

we have the same problem and I guess the reason is, that our german hoster domain Factory has updated their SSH-Ciphers.

RSA/DSA Keys smaller than 1024 bit are no longer supported due to security reasons. The hosters support suggests to change our software infrastructure...

Hi Iris,

I have the same problem. Could it be, that your Hoster has updatet webservers and brougt security level of sftp on higher level that DW does not support? In my case my hoster does it and DW schould have problem with it.

Hi Iris,

There is no change has been made in DW CC 2018 with respect to SFTP/FTP behavior.

Could you please check if your credentials are intact in server details dialog?

If no, please provide username/password and then try.

Please let us know if you still face problem

No we checked it all out, same credentials, same server details, in fact it just didn't work after the update with no changes made ...

we figuered within the checking out that in the dw library configuration folder (/Users/ihaeuschkel/Library/Application Support/Adobe/Dreamweaver CC 2018/de_DE) no ssh_hosts-file was created ... could this be the problem, but even with copying the same file into it, it didn't work ...

Any further idea?
