I have nextcloud 13.0.0 newly installed on Ubuntu 16.04 with apache 2.4 frontend and all works well on host http://omv.example.com/nextcloud on my internal network.
My web facing server is apache with SSL enabled and secured with a LetsEncrypt certificate.
I have added these lines to my front end apache config:
ProxyPass /nextcloud http://omv.example.com/nextcloud
ProxyPassReverse /nextcloud http://omv.example.com/nextcloud
ProxyPassReverseCookiePath /nextcloud /nextcloud
and I have added these lines to my nextcloud config.php:
'overwritehost' => 'www.example.com',
'overwriteprotocol' => 'https',
'overwrite.cli.url' => 'https://www.example.com/nextcloud',
Now when I access https://www.example.com/nextcloud, I see the login page, but the submit button is disabled:
<input type="submit" id="submit" class="login primary" title="" value="Log in" disabled="disabled">
What am I missing?
