502 error installing Dolphin 7

Hello i get a 502 error. I get to the install page. It says i have the correct permmisions. then i click next and it comes up with 502 bad gateway or unable to connect to proxy which dosent make any sense.

Can anyone help with this as I have the same problem :)

Should not be happening. Explanation of 502 errors. http://www.checkupdown.com/status/E502.html

You need to check with your host. That error points to a hosting problem.

I had this problem this morning after editing my /etc/network/ interfaces file,

# sudo /etc/init.d/networking restart

 * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces

 * Reconfiguring network interfaces...  

/etc/network/interfaces:10: unknown method

ifdown: couldn't read interfaces file "/etc/network/interfaces"

/etc/network/interfaces:10: unknown method

ifup: couldn't read interfaces file "/etc/network/interfaces"                [fail]

Could someone please check my address and see if my site comes up?  duvallocals.info

I could get it locally, but not on my phone. 

Kept getting 502 bad gateway..

Working from my home (IE) and phone (Android)..

 thanks so much Scott.

It was strange, I edited the interfaces file and didn't include 

# The primary network interface

auto eth0

iface eth0 inet static

address 192.168.1.116

netmask 255.255.255.0

(I had left these two lines out as suggested my one article, then another showed these..)

network 192.168.1.0

broadcast 192.168.1.255

gateway 192.168.1.1

I had run the sudo /etc/init.d/networking restart

and had no error before bed, get up this morning and looked at site stats and noticed no hits today.

Pulled up on home computer with the du.info address and worked fine, went to phone and got the 502 error, never showed on my home pc, I thought was strange.

Anyway, added the lines and run the network restart and it seems fine, thanks again for checking.

I guess there might be a better way to restart my network because I get this..

* Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces

You have a better command for restarting my network interfaces on my server?
