@Vinoth Palaniappan Thanks for reaching out. I have validated at my end with the character as '@', '%' with different combination and I couldn't observe any issue with authenticating the connector. I will suggest you to validate the below:
- I will first suggest you to type the password rather than copy paste as it include special character sometimes which is not visible directly until you are not pasting in command prompt (cmd) or pasting it with changing the encoding.
- Make sure that you have whitelisted the IP address of connector so the request is not rejected at your SFTP server as you can observe the same error as you have shared due to this. Please also validate there is no proxy in between that would reject the request or any network at the SPTP end rejecting the request.
Feel free to get back to me if you need any assistance.
