Getting "Key exchange negotiation failed" error in flow. Using ssh-rsa algorithm, I have tried with and without "ssh-rsa 2048" in front of the fingerprint. I get a formatting error with "ssh-rsa 2048" in front of fingerprint and without it, I get the key exchange negotiation failed. I am copying and pasting fingerprint directly from Putty. What other troubleshooting could I try to fix this error?

Re: Key exchange negotiation failed

If you generated your Key with Putty, it won't work. The SFTP-SSH connector support only supports keys in both OpenSSH and ssh.com formats. If your private key is in PuTTY (.ppk) file format, first convert the key to the OpenSSH (.pem) file format. You'll need to use Your finger print should be on MD5 format.

Re: Key exchange negotiation failed

Got rid of the error by connecting to WinSCP and getting the fingerprint there instead, it was different than the one provided in Putty. However now I am getting a "Test connection failed. Details: Access denied" error, very generic error message. Would this be due to not having enough permissions in SFTP?
