I got a error when i'm trying to connect sftp bank server from netsuite....

Provided host key does not match remote server's fingerprint.

please give me a solution for same.

I had this once and it wasn't until I put the same host key in to an editor and exposed non-printable characters that I realised I'd introduced linebreaks which weren't obvious. If you are 100% sure the key "looks" right and you've confirmed it with eth sFTP host, I'd double check that.

ok thanks, actually my host key is incorrect so i changed it after that it will run.
