The issue you are facing:
I am trying to migrate all of my data from Onedrive to Nextcloud with the aim of entirely replacing microsoft office with Nextcloud. I created a new sync folder on my Laptop and copied all of my Onedrive files to this new Nextcloud folder. It has uploaded only 10% of all the data.
It starts uploading when I force sync and then quickly stops, always because of a video file. The logs seem to indicate an issue with the size of the file not being the same as what was expected. I have attached the logs, I hope this provides more information.
Is this the first time you’ve seen this error? (Y/N): Yes, I just started using Nextcloud for the first time.
Steps to replicate it:
- Force sync.
- Wait a few minutes.
- The error reoccurs.
The output of your Nextcloud log in Admin > Logging:
[no app in context] Error: Expected filesize of 53784368 bytes but read (from Nextcloud client) and wrote (to Nextcloud storage) 52740096 bytes. Could either be a network problem on the sending side or a problem writing to the storage on the server side.

Any help would be appreciated, I really want Nextcloud to work so that I can replace Office with my own server. Nextcloud looks amazing!
