Yes, it does seem to be a firewall issue.
Can you confirm the below two points?
Do you have a remote perimeter server (PS) installed in your DMZ zone? Or the outbound connections go directly from SFG without PS.
If no PS, then check if telnet to remote server is working from your SFG server.
If you have a PS, then check if telnet is working from where you have PS installed.
telnet <remote_sftp_server> <sftp_port>

Hi,
You may want to use the SSHKeyGrabberProcess to retrieve the latest key from remote SFTP server and update SFTP begin session with the new key and try. It might fix your issue just in case your current KnownHostKey is not matching with the actual Host Key at the server.
The below links explain the steps to grab the SSH key.
How to use the "Obtain key from a Remote Host" option with a perimeter server:

SFTP Client Adapter > Obtain an SSH Known Host Key Automatically and Check It In:
https://www.ibm.com/support/knowledgecenter/SS3JSW_5.2.0/com.ibm.help.sftp.doc/SI_To_Obt_Hst_Key_Auto.html
Also, make sure you are not using both SSH Remote profile and then overriding the key in the BP configuration.

Hello,
