Unable to access remotely

Steps to reproduce

1.be on a network outside of your home network
2.attempt to connect by any means aka desktop app, internet page, android app
3.

Expected behaviour

When I first installed owncloud and got it setup I was able to connect when not on my home network but now for some reason I am no longer able to connect by any means when I am not connected to my home network. I even tried to setup a VPN to my home network and it still won’t connect to my owncloud server.

Actual behaviour

In the app it states no connection to owncloud at http://publicIP/owncloud. timeout Connection timed out.

Server configuration

Operating system:
Linux Mint
Web server:

Database:

PHP version:

ownCloud version: (see ownCloud admin page)
The web portal says version 10.7.0 (Stable)
Updated from an older ownCloud or fresh install:
I believe it has updated. I have my desktop set to auto update every morning
Where did you install ownCloud from:
I followed a youtube video a year or so ago on setting it up so I can’t remember for sure where I got it from

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results into https://gist.github.com/ and puth the link here.

I am not seeing this option and when I try and manually type it in it takes me back to the files area.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

or 

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Thanks for your help

If you can access from your home network, I don’t think the problem is related with ownCloud. It might be a networking issue.
