Steps to reproduce

Im using OpenSSH on Windows server 2022 to receive files via SFTP from remote servers. On the remote servers, I configured the IP address of the Windows server, username and password, and folder path in Windows that will receive the files. WIndows firewall has a rule to allow all incoming traffic on port 22. Windows server has joined domain.

It used to work fine, but after updating the openSSH version from 9.5 to 9.8, it stopped working. The remote servers give the error "peer reset the connection". Using WinSCP to access the Windows server also gives the error "connection abort". These are the logs produced in %programdata%\ssh\logs\sshd-session:

Expected behavior

Adding Windows server as SFTP server succeeds. Files sent from remote server will appear in folder on Windows Server.

Actual behavior

"Peer reset connection" on remote server. "Connection abort" on WinSCP. Files not sent to folder in Windows.
