Description Felix Botner

2016-09-12 16:45:16 CEST

Tried to upload a 190MB debian package to the selfservice. Brower got stuck and the upload never finished.

Browser dev tools said

Bad Gateway
The proxy server received an invalidresponse from an upstream server.

for the upload request.

Apache log file:
Im apache Error Log sieht man folgendes:

How long did the upload take exactly? You can see this in the network console of chromium.

not to long, got error messages in dev tools and apache after maybe 1 or 2 minutes, but the UMC loading screen never went away

patch

Apply the patch and set umc/http/max_request_body_size=0 and there is no size limitation anymore :)

Comment 4 Florian Best

And you need to set "umc/server/upload/max" because the UMC-Server checks also for the size of each uploaded file.

Thanks!

Do we need to set this variable also in a apache config file? I have applied the patch to Self Service. Should be fixed along with the next frontend update, otherwise the patch is lost.

Nothing needs to be done in apache. The default in apache is 0:
