Failure during copy from blob to sql db using ADF

I have this error right now. I can tell you that I have successfully imported other files. It's only this particular file with the issue. The import sits there for a long time so I actually think the connection is timing out. The log says:

Data Read: 1.18 MB Data Written: 0.00 Bytes Rows: 0

The difference between this file and the others is that this is a mutli column file (CSV) whereas other files as a single column

Hello,
3days ago, I was able to copy data from BLOB CSV to SQL Database by Azure Data Factory COPY  PREVIEW without any errors. I tried to do the same datas and process again today and got the same error message with you. It's so simple schema and less data. I think we had better send a support ticket to MS, because we couldn't get the next action from this message...
In addition, ADF COPY from SQL Database to SQL DWH was successful today.

The following is the error messge I got from ADF

I have the exact same problem ... it was working fine about two days ago and I was happily running pipelines from CSV files on blob to Azure SQL ... then all of a sudden they begin to fail with the following helpful message:

Failed execution

Database operation failed. Error message from database execution : ExecuteNonQuery requires an open and available Connection. The connection's current state is closed..

Skipped row count: 108

Execution location: West US

I wonder whether this is only occuring in West US or all data centres.
Is there anyway in which to increase the time the conneciton is held open for, either in the pipeline or SQL?

Thanks
