Amazon S3 - recurrent error SSL handshake failed. Endurance doesn't work

Hi,

I'm uploading a bunch of files to Amazon S3. Every 3 minutes a pop-up comes and I have to press Retry to continue sending the files (see screenshot below).

I'm using vrs. 5.19.2 (Build 11614) running on Windows 10

Bellow you can find the related log lines. It looks like a connection timeout, but why doesn't it resume? Is it possible to keep the connection alive when uploading to S3?

Thanks in advance
