Error while uploading a 1GB fil for restore

Hello,

On a instance of Moodle, I had backup a course. The file has a size of 1GB.

I try to upload this file, on course reuse > restore.

Everytime, I had a message error after a while "error connecting to the server"

I checked the parameters in php.ini:

max_execution_time = 600

post_max_size = 1500M

When I try with a 900MO file, it works perfect.

Any idea?

Thanks in advance!
