Connection closed when using the Invoke-PowerBIRestMethod to refresh dataset

We have a PowerShell script that uses the "Invoke-PowerBIRestMethod" to force a dataset to refresh.  The script has been working without issues for the past several months.  For the last week and a half, we have started receiving the error stating the connection was closed by the host.  At first it was very random but then in the last couple of days, the error is occurring consistently.

We pass in the workspace GUID, dataset GUID, and the file path that stores the password for the user. 

I have included a portion of our script (it uses parameters to pass in the workspace GUID, dataset GUID, and the file path that stores the password for the user) and the full error message below.

Does anyone have any insights as to what the issue could be?

Thanks,
