Disconnects During Synchonization
I have WinSCP running on multiple clients accessing the same server (Windows Server 2008 R2). The problem I'm having is that during synchronization, whether uploading or comparing, the connection seemingly randomly drops. Here are some logs when trying to upload synchronized changes.
WinSCP log:
Server side log at the same time period. The server logs in UTC, but it's interesting to me they are off by approximately 20 seconds. Is that significant at all?
It doesn't look like anything significant is happening to end the connection. The only thing odd I see is the timestamps. At timestamp 2022-08-31 21:31:52.229 you can see when WinSCP requests changing the working directory at the server. At timestamp 2022-09-01 04:31:39 the server changes the directory. After that at timestamp 2022-08-31 21:31:52.229 WinSCP requests to know what directory it's in (
Does anyone have any ideas what's going on here?

PWD), but then it just... Fails. The server shows the control channel closed, and WinSCP says it's disconnected from the server. The end.
Does anyone have any ideas what's going on here?
