Upload Code 201 but 0 bytes and/or HTTPError Response code 500 about hassio-nextcloud-backup

For nextcloud you have to configure php settings:

upload_max_filesize=256G
post_max_size=256G

Explanation:
In this example it's set to 256 GB, choose whatever you want. )

if nextcloud is running at nginx you have to set
client_max_body_size 0

if nextcloud is running at apache2 you have to set

LimitRequestBody 0
FcgidMaxRequestLen 1073741824

Explanation:
LimitRequestBody 0 disables the Limit
FcgidMexRequestLen is set in Bytes. In this example 5GB.

As I am running nextcloud at apache2, I confirm these settings for uploading backups to nc with a size up to 5GB. It could be, that the FcgidMaxRequestLen is also missing at nginx servers or has a very similar setting. Check your apache2/Nginx logs, they are very helpful. In my case, the usual upload max request lenght was set to 1GB. Now it's set to 5GB.

Uploads via frontend and/or client is not the same way as uploading via your HA instance, as the frontend chunks bigger uploads and the client uses a different connection type.

The addon is working, if nextcloud has the correct settings - i bet that's a solution for most of the open issues in this repo.
