Recommendation: To see whether your key file or password is correct, double-check with tools such as WinSCP. Ssh-keygen -f traditional_format_key_file -pĬause: Invalid credentials or private key content. To convert the key to traditional SSH key format, starting with '-BEGIN RSA PRIVATE KEY-', run the following commands: openssl pkcs8 -in pkcs8_format_key_file -out traditional_format_key_file PKCS#8 format SSH private key (start with '-BEGIN ENCRYPTED PRIVATE KEY-') is currently not supported to access the SFTP server. We recommend the Encode to Base64 format tool.Ĭause: The wrong key content format was chosen. Use a third-party base64 conversion tool. String ke圜ontent = Convert.ToBase64String(ke圜ontentBytes, Base64FormattingOptions.None) Use C# code: byte ke圜ontentBytes = File.ReadAllBytes(Private Key Path) Here are some samples you can use to generate the string: The original private key file is the one that can work on the SFTP linked service if you select Upload from the file. The private key content is base64 encoded SSH private key content.Įncode entire original private key file with base64 encoding, and store the encoded string in your key vault. If the private key content is from your key vault, the original key file can work if you upload it directly to the SFTP linked service.įor more information, see Copy data from and to the SFTP server by using data factory or Synapse pipelines. Message: Invalid SFTP credential provided for '%type ' authentication type.Ĭause: Private key content is fetched from the Azure key vault or SDK, but it's not encoded correctly. Recommendation: Set 'useTempFileRename' as false in the copy sink to disable uploading to the temp file. Your SFTP server doesn't support renaming temp file, set 'useTempFileRename' as false in copy sink to disable uploading to temp file.Ĭause: Your SFTP server doesn't support renaming the temp file. Recommendation: Check the error details from SFTP. Check detailed error from SFTP.Ĭause: A problem with the SFTP operation. Open port 1024-65535 or port range specified in FTP server to SHIR/Azure IR IP address. Recommendation: Check the firewall settings of the target server. Message: Failed to read data from ftp: The remote server returned an error: 227 Entering Passive Mode (*,*,*,*,*,*).Ĭause: Port range between 1024 to 65535 is not open for data transfer under passive mode supported by the data factory or Synapse pipeline.

Recommendation: Check the port of the target server. Please make sure the provided server information is correct, and try again.Ĭause: An incorrect linked service type might be used for the FTP server, such as using the Secure FTP (SFTP) linked service to connect to an FTP server. Message: Failed to connect to FTP server.
