» SFTP21 error = #4 (Algorithm negotiation failed) SFTP21 error = #4 (Algorithm negotiation failed) 4 Years Ago GlobalSCAPE Support 1 CuteFTP for Windows THE INFORMATION IN THIS ARTICLE APPLIES TO: CuteFTP Pro® 8.3.2 or earlier SYMPTOMS When https://kb.globalscape.com/KnowledgebaseArticle10351.aspx attempting a connection using the SFTP protocol, the following error is encountered: STATUS:> https://community.hpe.com/t5/System-Administration/sftp-failed-after-secure-shell-upgrade/td-p/4637317 Getting listing ""... STATUS:> Initializing SFTP21 module... STATUS:> Connecting to SFTP server... 192.168.20.135:22 (ip = 192.168.20.135)... ERROR:> Algorithm negotiation failed. ERROR:> The requested operation failed for an unknown reason. ERROR:> Can't connect to 192.168.20.135:22. SFTP21 error = #4. STATUS:> SFTP21 connection closed. CAUSE The SFTP server is using an encryption algorithm sftp21 error or cipher that is not supported by CuteFTP Pro version 8.3.2 or earlier. The most common ciphers causing this error areAES128 or AES256. (That is whatAlgorithm negotiation failed indicates.) You can also get this error just from providingthe wrong password. #4 error isa generic error saying connection/login failed. It just so happens in the example above, it was caused by bad ciphers. RESOLUTION sftp21 error = To resolve this issue, upgrade to CuteFTP Pro version 8.3.3 or later.Support for AES128 and AES256 ciphers was added in CuteFTP Pro 8.3.3. If an upgrade is not an option,ask the administrator of the remote FTP server to allow useof a different cipher. The default configuration of earlier versions of CuteFTP Pro provided support for TripleDES, ARCFOUR, CAST128, Twofish and Blowfish automatically. The allowed ciphers are accessible from the SSH2 Security Settings screen in Global Options.
