Download von ISOs dauert sehr lange bis er startet

Hallo,

Wenn ich von meiner Nextcloud eine ISO Datei downloaden will dauert es ewig bis es startet.
Ich klicke auf die ISO, dann vergehen ca. 5 Minuten bis der Download wirklich startet.
Es betrifft nur ISOs.

Nextcloud version (eg, 12.0.2): 17.0.3
Operating system and version (eg, Ubuntu 17.04): Ubuntu 18.4
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.41
PHP version (eg, 7.1):7.3

Is this the first time you’ve seen this error? (Y/N):N
