Let’s get right into it…

Why Does MT4 Say No Connection?

Few things are as headache inducing as a going to jump on your Forex trading software to capitalize on a new opportunity, only to have your MetaTrader 4Opens in a new tab. account tell you that it can’t connect – and you are left on the sidelines.

There’s only one real big reason that this error is going to pop up, too:

Because your internet connection isn’t working the way you think it is. 

Your Internet Connection is Down or Unstable 

If your internet connection is down, unstable, or unreliable – or even if MT4 simply reads it as down, unstable, or unreliable – you are going to have a whole bunch of problems staying connected. 

Luckily, reading how MT4 is interpreting your internet connection is relatively pretty simple and straightforward. 

All you have to do is look in the lower right-hand corner and see how the connection signal is color-coded to know (with some certainty) exactly what’s going on. 


A red internet icon lets you know that your account – and your installation of MT4 – has been completely disconnected from the internet and cannot establish a new connection, either. 


A red and green icon tells you that there is a direct connection to the server but it may be “misbehaving”. The internet connection isn’t as strong or as stable as it could or should be. 


Finally, a green and blue icon lets you know that your MT4 installation has connected directly to a data center. You shouldn’t ever see the “No Connection” error code when this indicator is present. 

How to Fix MT4 Saying No Connection

All you really have to do is click on the “connection button in the bottom right-hand corner of your MT4 software. You’ll immediately be presented with a list of servers you have connected to as well as the option to rescan servers.

Simply close out MT4, give it 30 seconds or so, and then restart the software from scratch.

Sometimes, though, upon restarting MT4 you are also going to have two real login to your account. 

Make sure that all of your account credentials are good to go. Errors here could be preventing you from establishing a connection as well.

Lastly, you want to make sure that your antivirus software isn’t blocking your ability to connect to MT4 or to MT4 servers. 

If there is a conflict be sure whitelist MT4 and give it internet permissions. 

That’ll resolve the problem once and for all.
