Online users of the Manifest portal may experience "504 gateway Time-out" in cases, where a process is taking up Manifests resources for more than 60 seconds.

This error may occur when a search is performed resulting in too many hits  (i.e. too broad a timespan) or when trying to open a large arrival-/departure declaration with many goods items (and many notifications).

At the moment there is no workaround for this error. Contact the servicedesk for help.
