I have a backup configure to azure blob and it used to work well, but some days ago, i received this error on email

I then deleted the backup and start it from scratch. But again, after uploading 40GB (full backup size), i have the same error on “Waiting for upload” stage.
I tested with a new backup and it works well with small files. When i put some “big” file (100mb or more) it gave the same error. On this “test backup”, i solved the issue changing the “block size” from 50 to 20mb. But in the “production backup” of 40GB this trick doesn’t work.
I noticed that in the end of backup, duplicati tries to upload a 80mb file, and then it gave the error message, tries to rename the “block” and the backup fails.
Why are duplicati uploading a 84MB file, if my settings are configured to 20MB block size?
How can i solve it or give more informations?
