After the 2H 2023 Major Upgrade, you may face similar errors to the following if you are using a different port than Port 22 for SFTP communication in Integration Center, Security Center or Intelligent Service Center:
"Missing/Invalid Destination and Scheduling fields Port",
"The standard default SFTP port is 22. We do not recommend you to change it to another SFTP port, as it needs additional approvals and can cause security issues. For details, refer to KBA-3148291."
Port 22 is associated with the Secure Shell (SSH) protocol, which is widely used for secure remote administration and secure file transfer. It provides encrypted communication and authentication mechanisms for secure access to remote systems and secure file transfers over unsecured networks.
Starting with the 2H 2023 Major Upgrade, Port 22 is the only port supported for SFTP communication. Custom ports are not authorized for communication as they can cause security issues.
NOTES
1. The Port information on Security Center and Integration Center (under Destination Settings tab) will have its value defaulted to 22 (refer to the What's New Viewer article).
2. If you had a previously scheduled IC job in a port other than 22 and wish to continue using it, please ensure the job is scheduled ahead of Production Release (likewise, any integrations already scheduled with any Port other than 22 will continue working)
