The MSDTC transaction manager was unable to pull the transaction from the source transaction manager

System.Runtime.InteropServices.COMException: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B)

Which show the two machines were able to communicate with each other, a transaction was started but then application sends a message to abort the transaction.

It happens intermittently, could anyone let me know what may cause an application to abort the transaction?

The code block causing this exception is of the given form

using (TransactionScope transactionScope = new TransactionScope(TransactionScopeOption.RequiresNew, new TransactionOptions() { IsolationLevel = IsolationLevel.ReadUncommitted }))
{
    // Data insertion
    // DbContext.SaveChanges()

    // Data update
    // DbContext.SaveChanges()

    transactionScope.Complete();
}
