Fixed with addition of config value:
‘trusted_proxies’ => [‘w.x.y.z’],
I have NC21 installed on Apache Linux behind an Nginx proxy. The proxy handles the SSL. My config.php includes the line:
‘overwriteprotocol’ => ‘https’,
but I am still stuck. The android client gets stuck at the Grant Access point. I tried the Linux client, and it was clear that the server thought I was trying HTTP instead of HTTPS because it complained that:
“The information you are about to enter is insecure” at the grant access point.
What am I missing?
