How to Flush Your DNS: Potential Fix for Login Issues

(Posted by Eliatan of the DolyGames Team)

Hey you guys, recently there have been a lot of various login issues, and they largely stem from something DNS (domain name system) related.

This isn't an absolute fix, but when you have login problems, it's worth trying to flush your DNS. So if you are getting really frustrated with screens that tell you "Can't retrieve server DNS," "tp.r2games.com not found," "This page cannot be displayed," these steps may help.

Just to clarify, flushing DNS is not a direct fix for loading issues. So if you're stuck at the 50% loading screen or any other number between 0 and 100, this doesn't address that problem. This is for if you can't even make it to loading the game. Slow or incomplete game loading can be due to an assortment of things, including slow internet.

For Windows

Open a command prompt (Win+r and type cmd) and enter:
ipconfig /flushdns

For Mac

Open a Terminal window (Applications --> Utilities --> Terminal, or Command+Space and search "Terminal") and enter:

OS X Mountain Lion or Lion

sudo killall -HUP mDNSResponder

Mac OSX 10.4 And Below          

sudo lookupd -flushcache 

Mac OSX 10.5 And Higher

sudo dscacheutil -flushcache 

Linux

There are a wild assortment of ways to go about flushing the DNS for Linux users, but this seems like the easiest.

In a terminal enter:

sudo apt-get install nscd
/etc/rc.d/init.d/nscd restart

Or you can give this a go (Thanks Meezan!)
sudo /etc/init.d/dns-clean start

After All That

Give your computer and router a nice little reboot :)

Hope this helps! No guarantee that it'll work every time, but at least some people have had success with it. Big thanks to my buddy Arty for helping me with info and clarity for this post!
