[DST-2:1103#451] Error while uploading backup

02.08.2021 13:59:00 [Error] Destination error: ${https://sqlbackupandftp.com/kb?id=DST-2%3A1103%23451|#[DST-2:1103#451]} Failed to upload “C:\Windows\TEMP\SYSTEM\Pranas.NET\SQLBackupAndFTP\backup\eazybusiness202108021356.zip” file. > Transfer aborted. Input/output error (451).

Started getting this error today and dont know what caused it since it worked fine until today. Subscription expired a few months ago but I dont see why this is an issue since it worked fine until now.

Windows server updates are all installed, using .NET Framework 4.7 and already saved a log file but it seems I cant upload it here.

What can I do to resolve the issue?

Update: Resolved the issue myself, most likely due to a storage problem. If you get this error message check if you have enough storage for the backup on all destinations
