Https proxy login disabled

I have nextcloud 13.0.0 newly installed on Ubuntu 16.04 with apache 2.4 frontend and all works well on host 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
   ProxyPassReverse  /nextcloud
   ProxyPassReverseCookiePath /nextcloud /nextcloud

and I have added these lines to my nextcloud config.php:

  'overwritehost' => '',
  'overwriteprotocol' => 'https',
  'overwrite.cli.url' => '',

Now when I access, 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?

Bump - is this thing on?

One thing you could try is to add the proxy as trusted in the nextcloud config.php:

‘trusted_proxies’ =>
array (
0 => ‘’,


Thanks for your response.

I actually do have ‘trusted_proxies’ configured and I’ve verified the IP address from the apache logs.
