Connect() is throwing "Could not negotiate" exception - WeOnlyDo Discussion board

Connect() is throwing "Could not negotiate" exception (wodSFTP / wodSFTP.NET / wodSFTPdll)

by jja, Wednesday, March 25, 2015, 22:54 (3529 days ago)

I'm running a test in C# & Visual Studio 10, and am attempting to connect to a remote SFTP site. I can connect fine with FileZilla. However, when stepping through debugger and using the WeOnlyDo.Client.FTP.dll, I'm seeing the following error when executing the FtpDLX::Connect() call.

WeOnlyDo.Exceptions.FtpDLX.ProtocolException: Could not negotiate diffie-hellman-group1-sha1.

I've confirmed the FtpDLX properties have been initialized as desired. Any thoughts as to what might be causing this error? Much thanks!!

Hi Jja.

I think you're using older version of wodFtpDLX.NET. We don't have such exception anymore, and diffie-hellman-group-14-sha1 was added on February 2015

http://www.weonlydo.com/FtpDLX.NET/ftp-sftp-ssl-net.asp?rnotes=1

so, I believe simple update will fix your problem.

Best regards,
Jasmine.

Thanks Jasmine! Looks like that's resolved my problem. I've noticed the "LicenseKey" property is no longer valid with this newer version of the FtpDlx class. Would you confirm? Thanks!

Hi.

LicenseKey is there, but you probably downloaded DEMO from our website. If you're licensed customer, you should request update from our website at

http://www.weonlydo.com/index.asp?update=1

and obtain it through our customer support system.

Kind regards,
Jasmine.

Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.

The SFTP ocx is one of the finest pieces of programming I have seen. It worked out of the box...
