Host is not communicating for 15 seconds

2023-03-28 14:24

Hello,
I am keep getting below error while operating on WinSCP 5.19.6

Host is not communicating for 15 seconds
Note: If the problem repeats, try turning off 'Optimize connection buffer size'

Is their any way to fix this issue?

Regards
Renju

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

5.21.7 log is complete. I did the same actions and compared the size.

You will get the error alert window with "abort" button and then 2 more alerts with more cancel and abort.
