Using proxy server within nextcloud

ℹ️ Support
1

I’m a newbie when it comes to nextcloud.
I’m running a nextcloud 10.0.1 installation on a LAMP server.
A firewall is setup to allow incoming connections over 443. And a https_proxy server is used when I need to update the server using yum and connecting to the internet.

Right now when I go to Apps within the webgui it takes a while to see all the apps. A message appears on the top of the screen saying the page could not be loaded. Refreshing in 5 seconds.

Looking in the logs I see:
Could not get categories: cURL error 28: connect() timed out!","level":3,"time":"2016-09-28T13:05:03+00:00

and

Could not get application: cURL error 28: connect() timed out!

I think the installation is unable to connect to the internet due to way we setup the host.
Is there a way to add a proxy server so that the nextcloud installation can for new versions of apps and for the installation?

Thanks!

This might helps you:

You can make a alias in your ~/.bashrc file :

alias curl="curl -x <proxy_host>:<proxy_port>"
Another solution is to use (maybe the better solution) the ~/.curlrc file (create it if it does not exist) :

proxy = <proxy_host>:<proxy_port>

Try setting the proxy url and authentication in the config/config.php file. For example,

‘proxy’ => ‘myproxy.server.ext’,
‘proxyuserpwd’ => ‘username:password’

Take a look at config/config.sample.php for more information.

Looks like this option helped getting all the internet related connection errors out of the log. The Admin pages and Apps pages load a lot quicker now.

Thanks for the help!

Although it looks like to proxy is working, I’m still getting errors. Especially when nextcloud is checking for updates:

I’ve anonimized the ipaddresses. 1.1.1.1 is my outside IP and 2.2.2.2 in my internal squid host.
Curl is stating it gets a permission denied, I cannot find any clue of this in the logging of the squid host.

“cURL error 7: Failed to connect to 2.2.2.2: Permission denied”

Also it looks like the installation is still looking at owncloud.

\/var\/www\/file\/settings\/Controller\/CheckSetupController.php(195): OC\\Http\\Client\\Client->get(‘https:\/\/www.own…’)\n#10

But looking at the config.php I see it needs to look at https://updates.nextcloud.org/updater_server/, but this is turned off.

‘updatechecker’ => false,
‘updater.server.url’ => ‘https://updates.nextcloud.org/updater_server/’,
‘updater.release.channel’ => ‘stable’,

And when I telnet to the squid proxy and running these commands, all is okay.

root@centoshost config]# telnet 2.2.2.2 3128

Anyone any ideas on how this can be corrected?
