Resolved NextCloud, WebDAV, upload errors for large files

[MicheleB]

Hello,
I've a problem with NextCloud (installed using Plesk's extension) and WebDAV connection.
If I try to upload a "large" file (e.g. 800MB) I receive the "server error".


I've tried to search a solution on the NextCloud community forum and it seems that the issue is fixed if I change the default value in the “client_max_body_size".
So, how can I change “client_max_body_size" on Plesk?
What is the exact configuration to set in the "Additional nginx directives" (or in the "Panel.ini Editor")?
Last but not least, is there a maximum value not to be exceeded for safety reasons? For example, is dangerous if I set a value of 10G (the same value that I set in the "upload_max_filesize" for the PHP settings)?

Thanks.

If I use this instruction on Panel.ini (using "Panel.ini Editor" extension) is safe or could create issues on the server?

[webserver]
nginxClientMaxBodySize =

Is there a way to setting the "client_max_body_size" for a single hosting and and not the whole server (using for example "Additional nginx directives")?
