Error installing collabora online

Hello,

I’m trying to install Collabora Online on Nextcloud, but I’m getting this error

cURL error 28: Operation timed out after 120000 milliseconds with 188284483 out of 345741448 bytes received (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Do you have any idea what the problem might be?

Thanks.
