The trust relationship between the primary domain and the trusted domain failed.

We are unable to connect to a destination server over SFTP

Using WinSCP 5.15.19 (Build 10071) with “Commander” interface on Windows server 2016 OS.

SendToSFTP object : The trust relationship between the primary domain and the trusted domain failed.

Both the servers are in same domain. We can connect to destination from another server within same domain.

What is "SendToSFTP object"?
I believe that this is related to this thread, right?
