Greetings,
We have about 100 reports scheduled to run every night for about a year which were working fine until a couple days ago.
Today and yesteday only 25% of all reports were delivered to our server.
The rest are failing with the following message
| Information | | Reason: | This report failed to successfully transfer. | | Note: | The transfer process may have left behind incomplete report files on the destination server. |

We are seeing the following information in our logs (actual username was replaced with *FTP_USERNAME*):

This issue began happening very recently.
Server has plenty of storage available, more than enough bandwidth and compute to handle 100x the capacity of current reporting and had 100% uptime for FTP service during attempted data transfer.
Is there a place where I can get more meaningful information about the cause of this error or something that I can do on my side to ensure delivery of reports?
