Add 10.0.14.11
to trusted_domains
like so:
'trusted_domains' =>
array (
0 => 'nextcloud.mydomain.com',
1 => '10.0.14.11`,
),
What URL did you use to install originally?
(you can redact it/modify it for privacy, but basically give me an idea of what you used).
And your Nextcloud VM’s NGINX is basically this?
