Timeout detected. (control connection)

Hello,

I have a recurring timeout issue when uploading large files on a FTPS server.

The only log I have on the client side :

. 2020-06-08 11:19:34.088 Data connection closed
. 2020-06-08 11:20:24.335 Timeout detected. (control connection)
. 2020-06-08 11:20:24.335 Copying files to remote side failed.
. 2020-06-08 11:20:24.335 Got reply 1004 to the command 4

On the server side :

I have asked my network admin to check on the firewall if there is a mechanism that closes long sessions but to be sure I would like to know if you can see something in these logs that I am missing.

Thank you in advance.
