@Teradi: change Settings->Advanced Settings->InternetConnectionSettings.preferredipversion to IPV4_IPV6 and restart JDownloader
Issue is caused by non working IPv6 connectivity.
JDownloader first tries IPV6 because your OS signals valid IPv6 connection and fails with connection timeout

That takes a few seconds before the timeout happens and JDownloader tries working IPv4 next

You might wanna check your setup ,why it has a valid IPv6 but seems not to work properly. You can check it with
ipv6-test.com
