What Causes Common Error in MT4

Common error in MT4 is caused by the connection lost between your MT4 trading terminal and broker server.

Connection can be lost because of:

  • bad Internet connection and
  • because of wrong metatrader login details that are preventing connecting to the broker server.

Bad Internet Connection

Internet connection can be lost for different reasons and one of them is a weak Wi-Fi signal if you are using Wi-Fi connection.

If you are traveling then Wi-Fi signal can be lost in tunnels where Wi-Fi signal is weak or there is no signal, then switching time between base stations where you lose connection because you are traveling very fast and signal is not switched fast enough between base stations.

Wrong Login Details

If you enter bad login details like:

  • password which is usually the first problem or
  • server address
  • or account ID

then you will not connect to the broker servers.

On the other hand the cause of common error in MT4 can be because of MT4 itself. MT4 can sometimes run into errors and lose internet connection. That is usually a short lasting issue that is fixed on its own.
