Exporting To Azure SQL from Local SQL Database Failure

I have a local SQL Server 2012 database that used to export tables and views to Azure SQL daily. It's been working flawlessly for 3 months.

The export tasks were created by the SQL Server Studio Import/Export Wizard. They were saved into a SQL Server SSIS package and ran daily by a SQL Server Job.

Issue I am having:

For the past few months, the export process have been failing randomly with multiple errors. It mentions that the connection has dropped. I don't think this is the problem.

I can run SELECT statements against the Azure database in SSMS with no problem. The Azure database is read by Microsoft Power BI with no problem too. So I think the problem is local to my network.

Sometimes it works fine, other times it fails. I've noticed that smaller tables export fine, but larger ones like the error above have about 12,000 records. It fails randomly in different amount of records.

Has anyone any experience with what is going on?

Thanks!
