The ‘Common Error’ message in MetaTrader 4 (MT4) occurs for a variety of generic issues. Most commonly it occurs when an internet connection is too slow or is being disrupted. MT4 requires a fluid, direct internet connection and to be at a minimum speed to stay connected.
How do I fix the ‘Common Error’?
Please try the following procedures to resolve the issue:
Close any charts that are still loading or frozen
Close platform and restart your computer
Check your connection. If running fine, turn off router – leave for about 30 seconds and then turn back on
Try temporarily disabling anti-virus software or internet security programs
If you have another computer, try it on there first to see whether it is a connection or computer problem
Make sure you have selected the correct server at Log-In. For example, if you are on the Demo account, please connect to the ‘Demo Server’
On the right-hand corner in the bottom, click on the connection bars icon. Click ‘rescan servers’. If this does not change the server connection status, select another server centre.
