Does it always fail on the same file -
Can you ever upload that file (even manually, not as a part of synchronization) without an error?
Hi, it failed on all files I tried to upload. And I did try to upload any file manually but got the same error.
For your reference, here I recorded what I did: https://www.screencast.com/t/K48FFJNwMlFz
And here's what I set in the Endurance in my preference, other than that I have kept everything as default: https://www.screencast.com/t/HlGJ63x2h
Here I'll try to dissect what happened when I uploaded files as shown in the video:
1. Right clicked a certain file and chose "Upload";
2. Uploaded to the root directory of the remote FTP server;
3. "Lost Connection" error alert box popped up, WinSCP tries to reconnect continuously every 1 second (as I set up in Endurance);
From now on, two scenarios would happen:
Scenario A (when uploading test1.txt):
I clicked "Abort" AND MOVED the cursor a bit
a1. The Reconnect time changed to 30 seconds;
a2. I clicked "OK";
a3. WinSCP asked me to connect the FTP server again;
a4. After I logged in the FTP server, the remote directory shows the file I just uploaded (test1.txt).
Scenario B (when I uploading text2.txt and AdminAttendanceTypes_jp.asp):
I clicked "Abort" BUT DID NOT move the cursor at all.
b1. The Reconnect time remains at 1 second;
b2. Immediately the remote directly refreshed and successfully listed all files I uploaded.
Again when I tried to upload using FileZilla (as well as CuteFTP, which I've been trying these days), no such issue has happened.
