In this article, you will learn how to troubleshoot the "Unable to connect to customer database" error in TimeXtender Master Data Management. This issue usually happens when the user is either working from a different place than usual; normally from home.
Troubleshooting
To find out what is causing this issue, you should first start by opening PowerShell on your machine. When you have done that, you should try to execute the following command:

If your database is hosted on the TimeXtender’s servers try this command:
Test-NetConnection -ComputerName mp77op1ebc.database.windows.net -Port 1433
If your server is not hosted on TimeXtender’s servers you should replace mp77op1ebc.database.windows.net with your company's database path. For example:
Test-NetConnection -ComputerName xxxxxxx.database.windows.net -Port 1433
