Desktop Client - Connection Closed



This still happens - Server Community (Centos), Client 2.5.3 (stable, Debian/Manjaro).
In my case its just with uploads that the server closes the connection - and it started when I upgraded my ISP connection. Throttling down my client’s upload speed to 200KIB rids me of that nag - but an upload from the web browser (FF) works like a charm at full speed (abt 1.2MiB). If both cases are handled by the same code on the server, then that would suggest an issue in the client code…
Any Ideas? Thanks a lot, weHe
