Lost connection - ("Timeout detected. (control connection)","Copying files to remote side failed.

Hi,

A time out error is popping up when I try to upload a Zip file into a remote server which is having Windows Server 2019 OS.
I'm trying to upload the Zip file using my Laptop which is having Windows 10 OS.

I went through below topics, but no luck.

Does anyone have a lead why the "Control Connection" is closed?

Please follow attached Screen Dump and Session Log file.

Thank You!

Did you try to increase connection timeout?

If that does not help, please post complete session log file on level Debug 2.

Can you upload the file anyhow? Like using a different FTP client?
