Hi All,
I have generated GUID password to connect with SFTP server, I am facing an issue like
```FTP_UNSUPPORTED_ENCRYPTION_ALGORITHM```
I was able to connect successfully but it is throwing error now.
I have searched in help and showing algorithm not supported.

Can any one help on this issue to connect successfully.

Thanks

This happened to us as well. It's likely due to the lack of supported ciphers on the SFTP server. Is this an SFTP server that you manage? This is from the SuiteScript docs about N/sftp
```Only CTR (and not CBC) ciphers are allowed. Your SFTP server can use the following
encryption algorithms:
■ AES 128-CTR
■ AES 192-CTR
■ AES 256-CTR
■ RSA
■ DSA
■ ECDSA```

Thankyou <@U022VLF1Q7N> Yes SFTP provider having AES supported cipher, It is actually working in production but not in sandbox. It was working in SB also but after sandbox refresh i am facing this issue.
