"an unknown error has occurred" when uploading a MB size file

[sergiu_oanes]

I ran Nextcloud under a docker container. Uploading bigger files (talking about MB) I get an error “an unknown error has occurred” . Uploading smaller files works with no issues.
I don’t seem to find any settings to increase file size upload.
Any ideas?
thanks

HI,

I think is related with this bug

Can not upload files larger than 10MB on RPI4

@nachoparker Can not upload files larger than 10 MB with the web inteface or sincronize with the windows app. I’m using: Raspberry pi 4 b NextCloudPi_RPi_07-20-19 image In a Raspberry pi 3 b+ with stretch image (fully updated) I don’t have any problem with uploads and I can upload files larger than 2GB. After the upgrade to Buster (ncp-dist-upgrade) the upload problems start to happen and are the same from the buster image

Try without modsecurity activated

issue fixed.
I created an additional config file on ngnix proxy container and specify the max body size.

Thanks for posting your fix sergiu_oanes

I used this guide:

(Just as a help for new users like me)

I came across the same issue and in fact for me the solution was to add a vhost.d file for my specif host. Another I believe also good solution is provided by nextcloud itself:

https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/with-nginx-proxy/postgres/fpm/proxy/uploadsize.conf

See in the folder up on how the nginx conf is used during the build process of a new nginx image.
