So und der Provider hatte gesagt das dies auch am Router liegen kann. Da der Router die großen Dateien vielleicht nicht richtig annehmen bzw ihm diese zu groß sind und er dann ein Timeout macht. Deswegen werd ich die Tage mal ein Router update durchführen mal sehen ob das klappt.
Mit freundlichen Grüßen
