I just started testing nextcloud for my home environment. I spun up a Ubuntu server 18.04.4 virtual machine and installed nextcloud via snap. I’ve uploaded roughly 2GB worth of images via the desktop client and am attempting to view said files via the gallery in the web browser. I’m noticing that the small images (approximately less than 15MB) generate a preview and open in the gallery just fine while images that are (approximately larger than 15MB) fail to load. Attempting to open a large image results in a “Error loading filename.jpg” exception being thrown. I suspect something is running out of memory, but i’m not sure where to look or what to reconfigure. What do I need to do to correct this?
Nextcloud version (17.0.3):
Operating system and version (Ubuntu 18.04.4 LTS):
Apache or nginx version (not sure - NextCloud was installed via snap):
PHP version (not sure - NextCloud was installed via snap):
