Nextcloud behind Apache Proxy causing 404 error

ℹ️ Support

Nextcloud version (eg, 18.0.4:
Operating system and version (eg, Ubuntu 20.04):
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 7.4:

The issue you are facing: When I access my nextcloud from my network using 192.168.0.11, it works fine. I reach a log-in page and can upload and download files . However I want to have it accessible from the internet, so have set up a domain nc.example.com, and forwarded the dns… This works fine.

I have an apache proxy setup, listening on 433 and proxying to the internal nc instance, when I try and access from the outside sustem I get a 404 error… I basically copied and pasted the nc.example.com.conf file from another working proxy and tweaked the commands… The config.php might be a little more troublesome… I have read and attempted to tweak that with no success… I feel I am going in cirlcles, and am pretty sure that I am missing something glaringly obvious, but Google isnt my friend on this occasion
For clarity the proxy is 192.168.0.7, the server is 192.168.0.11 and the url I am using to access from outside is https://nc.example.com
Thanks in advance

Is this the first time you’ve seen this error? N)_:

Steps to replicate it:

  1. Log in using https://nc.example.com

To whoever tidied up te format, Thank you very much… I guess that shows my noobness :slight_smile:

Problem solved, needed
‘overwrite.cli.url’ => ‘http://nc.example.com/’,
‘overwriteprotocol’ => ‘https’,
‘overwritehost’ => ‘nc.example.com’,
adding to the config.php file

Thank you for this post, I was missing the overwritehost setting :slight_smile:
