Reverse proxy operation with https only mod_proxy. NextCloud won't do redirects to https in location headers. ProxyPassReverse must be used.

- ProxyPassReverse http://www.electricbrain.com.au/nextcloud

NextCloud container environment variables

       - OVERWRITEHOST=www.electricbrain.com.au
       - OVERWRITEPROTOCOL=https
       - OVERWRITEWEBROOT=nextcloud

trusted_domains:
For anyone else having trouble with this, when it's asking for a trusted domain, it's the domain you GO TO to access NextCloud...not where you're trying to access FROM
