direct eqsl upload failed

[dl4bbh]

With the actual installed version (5.3.3) the direct upload to eQSL failed. The message "Wait uploading data" is shown, the data are uploaded, but the message don't finish and the qso's in Rumlog don't change from "W" to "S".
Whats the mistake?

Maybe the server was down? Currently it is working fine here.
