Scheduled Task no longer running: Exception code: 0xe0434352

I had a scheduled task that has ran successfully for over two months. On March 12th/13th the task stopped running and I started to receive the following error each time it tried to run each day following the March 12th/13th date.

What confuses me the most is that it successfully ran over two months and then stopped working. I checked with my networking team and they nor I can think of any changes occurred that would affect this.

When I manually execute the program with the same execution path stored in the Task Scheduler it runs successfully.

Any advice is appreciated and troubleshooting suggestions are encouraged.
