Enterprise Client Community

We're using a filedownloadbutton with a DefaultBufferedStreamContent behind. So far this worked without problems, but one new customer gets a 502 error when executing that download:

Server returned HTTP response code: 502 for URL:
https://[customerURL]/[applicationName]/ccbuffer/BUFFERED_1457682048706_776.ccbuffer;jsessionid=[sessionID]

Any ideas what to do in this case?
Thanks in advance.

Hmmm,

502 = Der Server konnte seine Funktion als Gateway oder Proxy nicht erfüllen, weil er seinerseits eine ungültige Antwort erhalten hat.

Seems that there is some proxy in between which seems to tell the client that the server sent some invalid response via the proxy to the client...

Are you sure that the (CaptainCasa/Tomcat) Server is passing a back some valid content (and not e.g. "null"-content for some reason). There is some logging (INFO mode) in the server log of CaptainCasa when some download of buffered content is requested. Could you check this logging?

Thank you for your reply.

The problem has disappeared at the customer after a server restart, so it doesn't look like an application- or Captain-Casa-problem.
