Nextcloud

Iframe in 16.0.X

I followed this https://help.nextcloud.com/t/solved-nextcloud-16-how-to-allow-iframe-usage/52278

Modify /var/www/nextcloud/lib/public/AppFramework/Http/ContentSecurityPolicy.php

protected $allowedFrameDomains = [
’https://core.dev0.sh’,
];
/** @var array Domains which can embed this Nextcloud instance /
protected $allowedFrameAncestors = [
‘\'self\'',
'https://core.dev0.sh’,
]

I also had my previous .htaccess which does the basic "X-Frame" options allowing core.dev0.sh
